California wants to preserve mountain lion DNA, so it spent $100 million on a highway bridge

While for humanity roads are essential means of communication, for animals it is the opposite: a barrier that can be lethal. In fact, every year millions of animals die trying to cross roads that cut their habitats in half: we see the same thing in Iran with the Asiatic cheetah that in the India, where elephants are run over (although yes, with trains) is one of the big problems of its railway system. One of the solutions proposed by conservation biology are wildlife steps: an infrastructure, whether a bridge, tunnel or walkway, that allows animals to move safely through their domain by crossing roads or railway tracks. California just took this idea to another level with the largest structure of its kind ever built. The megastep for California pumas. It is about the Wallis Annenberg Wildlife Crossinga colossal plant bridge about 64 meters wide that crosses the US-101 highway as it passes through Agoura Hills, in Los Angeles. The structure has more than 11.8 million kilos of concrete, 82 bridge beams and more than 6,000 cubic meters of living soil to house more than 50 species of plants native to the region. The idea is to faithfully recreate the coastal sage scrub or coastal sage scrub, aromatic shrubs that are abundant in the area, but on one of the busiest highways. The project is a public-private collaboration that started formally on Earth Day 2022 and has cost $114 million. Its inauguration is scheduled for autumn of this year, thus becoming the largest wildlife crossing in the world. California Government Why is it important. The United States National Park Service has spent decades documenting that mountain lions in the Santa Monica Mountains are genetically isolated by roads and urbanization. And an isolated population is doomed: it does not have genetic exchange with other groups, there is endogamy, genetic variability is lost and the species loses its capacity to adapt. That is to say, the passage of US-101 not only kills animals by being run over, but it is also an evolutionary trap. That said, the bridge is not an infrastructure that will benefit exclusively the puma: it is also designed for red lynxes, foxes, coyotes, reptiles and a long chain of species whose mobility is essential for the ecosystem. Finally, the structure is framed within the California 30×30 objectivewhich aims to conserve 30% of the state’s coastal lands and waters before 2030, in this case connecting the protected spaces of the Santa Monica Mountains with the environment. Context. Wildlife passages are not something new: the first were built in the 50s of the 20th century, in France. In fact, Europe has been developing this technology for more than 70 years and has a long list of structures of this type. What is unique about this project is not so much the structure itself, but its scale and location: it is in a huge city and crosses a 10-lane highway where More than 300,000 vehicles pass through each daynot on a secondary road in deep America. However, there are already promising precedents such as the recently inaugurated Colorado’s Greenland Wildlife Overpass on I-25, connecting approximately 15,800 hectares (39,000 acres) of habitat for deer, elk, mountain lions and bears. Scientific literature also supports the bet: after analyzing 89 fauna passages in Europe, North America and Australia, this study published in Biological Conservation concluded that they are highly effective and that they reduce animal mortality due to roadkill by up to 90% compared to unprotected stretches. Other wildlife passes. Although the Wallis Annenberg Wildlife Crossing will be the largest in the world, there are other wildlife crossings (mainly in Europe) equally ambitious: Natuurbrug Zanderij Crailooin the Netherlands. At 800 meters long and 50 meters wide, it is the longest ecoduct in the world. Doñana National Park It has a network of wildlife crossings and ecoducts built specifically for the Iberian lynx, whose 80% of deaths occur due to being run over. On the A4 highway in the Lower Silesian Forest in Poland there are 15 ecoducts and wildlife crossings. It has been monitored for three years its use by wolves, ungulates and other carnivores. Veluwe ecoduct network in the Netherlands. Nine ecoducts in a natural area of ​​1,000 square kilometers, with almost 5,000 deer and wild boar crossings documented in a single year. Ecoduct on the Türkiye – Central Europe highway. It was built after multiple attacks by brown bears, achieving reduce collisions to zero. Yes, but. Despite its potential ecological value, the project has faced criticism for its high cost: It started with a budget of 92 million and in addition to being delayed, it will end up costing approximately $114 million. In addition, there are those who wonder whether a single structure is enough to save an entire population, suggesting that it is more necessary to implement smaller-scale but more numerous interventions rather than a single megaproject. From a strictly scientific point of view, the effectiveness of these steps is neither automatic nor guaranteed. A paper published in the Journal of Applied Ecology cautions that most available studies measure the number of crossings but not the actual impact on population viability, and that population-level effects remain difficult to quantify. Furthermore, design matters: those structures less than 20 meters wide are used noticeably less by animals. And if it has a bad location it can end up being useless. We will have to wait years of monitoring the Wallis Annenberg Wildlife Crossing to determine its effect.

The traffic jams in Valencia are hell. And a bridge over the Turia aspires to resolve the chaos between the V-30 and the A-3

Traffic jams for miles and with a regularity that seems almost infallible. Valencia has a problem with traffic jams and the connection between the V-30 and the A-3 is one of the hot spots every morning. They explain in The Provinces that the growth of the city leaves 800,000 residents inside… surrounded by 800,000 residents of the surrounding towns. With some infrastructure built decades ago For a much smaller number of residents, roads and the main Valencian roads are clogged with an assiduity that punishes the neighbors day after day. But of all the roads, V-30 is the most marked. The road has problems along its entire length. The new port terminal anticipates more complications looking to the future but other hot spots such as the connection with the A-3 is one of the critical steps usually indicated. To begin to alleviate the situation, the Ministry of Transport has given the green light to the construction of a remodeling of the link between both roads to facilitate traffic between the A-3 and the V-30. A new bridge to alleviate the situation The Ministry of Transport has published approval for the action on the link between V-30 and A-3, which includes a lane expansion and the construction of a new bridge. In total, nine structures will be affected, of which six are newly built. The project will have a budget of 56 million euros (VAT included) and will try to unclog an area that is constantly overwhelmed, especially during peak hours. The remodeling, They explain on the ministry’s websitewill have the following interventions: New planned structures: Bridge parallel to the existing one over the Turia riverbed that will also serve to bridge the crossing over the V-30. Underpass at the A-3 junction and the Puerto-Madrid branch (2 structures). Cycle-pedestrian underpass under the Valencia-Puerto branch. Cycle-pedestrian walkway over the Valencia-Barcelona branch. Existing drinking water pipe protection structure. Planned expansions on existing structures: Expansion of the underpass of 9 d’Octubre Avenue. Extension of the pedestrian walkway over the branches: Madrid-Barcelona, ​​Puerto-Madrid and the V-30 service road. Expansion of the pedestrian walkway over the A-3. In the case of the action on the A-3, the road will be expanded to four lanes towards Madrid. These lanes will be available to drivers from the interchange to the airport access. The objective is to facilitate the flow of traffic on a link that, right now, has become a bottleneck. in the diary Levant They explain that the situation is so complicated that, like a domino effect, the traffic jam usually extends to the V-31 highway as drivers try to find some other alternative route to the junction that forms there. In addition, the expansion of the lanes is also good news in order to save the high volume of trucks that begin their journey in the city port and take this road to begin their route to Madrid. Right now, the volume of cars is so high that the traffic jam is not only found on the A-3 towards Madrid. The branch from V-30 requires a long turn that reduces the speed of the cars. Between an A-3 with very dense traffic and slow access, the right lane of the V-30 ends up suffering all the punishment, being completely collapsed during rush hour. In addition, the residents of Xirivella, next to the road, will have acoustic screens and trees installed to reduce the sound of traffic and mitigate the visual impact of the structures. This was a demand that citizens had been demanding for some time and that had not been executed.

Spain has been building a bridge with China for years. Now it is the European Union that needs to cross it

Pedro Sánchez is going to land in China this week for the fourth time in three years. No other Western leader comes close. Why is it important. What seemed like a diplomatic eccentricity has become a trend. A year ago, Spain seemed an outlier in Europe due to its favorable and close stance towards China. Today it is France, with its calls for tougher trade measures against the Chinese government, who seems isolated, according to analyst Noah Barkin in his specialized newsletter. Watching China in Europe. The context has changed everything: the war in Iran, the volatility of the Trump government and the tariff as a political weapon have pushed Europe towards where Spain already was. The context. In recent years, Spain has attracted a constellation of Chinese companies while maintaining a discourse of rapprochement with China that the rest of the EU viewed with skepticism, if not suspicion. The map of Chinese presence in the country is already considerable: The result of all this rapprochement is also reflected in capital flows: Chinese investment in Spain went from 149 million euros in 2024 to 643 million in 2025, an increase of 331% in a single year. Nevertheless, has done little to reduce Spain’s large trade deficit with the Asian giant. The pattern is known: investment arrives, but Spanish exports do not grow at the same rate. Openness has a price. Between the lines. Barkin describes it like this: Pedro Sánchez has positioned himself as the most openly pro-China and Trump-critical leader in Western Europe. This gives Spain a position as unique as it is uncomfortable. Being China’s favorite interlocutor on the continent means assuming the diplomatic costs of that position when the EU needs to maintain a common voice vis-à-vis China. The contrast. While Spain opens its arms, the European Parliament cautiously reopens its ties with China after eight years of distance. A delegation of MEPs visited China this week on the first official trip since 2018, with a clear message, according to coverage by Traffic light China: commitment does not mean concession. The European Union negotiates with one hand and shields with the other. Spain, on the other hand, has opted for the extended hand, practically alone. The big question. Is Spain a pioneer or a lever? A pioneer sets the path that others end up following because it is the right one. A lever is an instrument that others use for their own purposes. Barkin warns that Spain is following the Orbán model: welcoming Chinese investment without the necessary checks and balances. The comparison may be unfair in its nuances, but it points to a very real risk: that the Spanish opening strategy lacks the reciprocity that Europe needs to negotiate as a bloc.

A municipality in Cáceres has waited more than 30 years for its bridge with Portugal. After moving wind and tide, it is already on its way

Cedillo, the westernmost town in Extremadura, has been separated from its Portuguese neighbors for more than thirty years by a river that, paradoxically, has always united them. The solution is easy: build a bridge. The issue is that its approval and construction has been in the works for years. Now it seems that things are finally moving forward. The problem. Cedillo (Cáceres) and Montalvão-Nisa (Portugal) are separated by just 13 kilometers in a straight line. But by car, any trip between both towns requires a detour of between 100 and 120 kilometers. The reason: the dam that Iberdrola manages at the confluence of the Tagus and Sever rivers. Until 1995, residents on both sides could cross it freely. That year, with the entry into force of Schengen AgreementIberdrola closed access citing security reasons. Since then, it has only opened on weekends, with a security guard and at controlled hours. “We are brother peoples absurdly separated,” counted in 2021 to El País the mayor of Cedillo, Antonio González Riscado, who has been in office since 1987. How did it get here? The bridge project has been circulating through offices and negotiation tables for decades without finally coming to fruition. In 2011, the Provincial Council of Cáceres, then in the hands of the PP, renounced some European funds destined for the work, according to account The Country. When the PSOE recovered the institution in 2015 and requested them again, Europe had already denied them. The project became a political bargaining chip for years. The turning point came in March 2023, when the Ministries of Transport of Spain and of Territorial Cohesion of Portugal signed a joint declaration committing to promote the initiative. Just over a year later, in October 2024, both governments signed in Faro an international agreement which established the definitive legal framework to build the bridge. According to this agreement, Portugal assumes the design, construction and financing of the main structure, while Spain facilitates the permits and procedures in its territory. The works have already started. In October last year, the machines began to move on the Portuguese side with the first land preparation work. The award went to the company Alexandre Barbosa, according to counted The Extremadura Newspaper. The bridge will be about 160 meters long and 11.5 meters wide, with two twin concrete arches that avoid placing pillars in the riverbed. In fact, as the media reports, this last technical solution was key for the bridge to obtain the favorable Environmental Impact Declaration. The total cost exceeds 19 million euros. Spain does its part. In November of last year, the Ministry of Transport and the Government of Extremadura they signed an agreement to coordinate the work on the Spanish side. The Board assumes the bidding, construction and financing of the accesses to the bridge in Extremadura territory, with an estimated budget of just over 5.1 million euros distributed between 2025 and 2028. Once the work is completed, the infrastructure will become the property of the Board of Extremadura, which will also be responsible for its maintenance. What this means for the area. The bridge is going to solve a problem that has been on the lips of the surrounding towns for decades day after day. Just like counted El País, there are residents of Cedillo who have been hearing about the bridge all their lives and whose lives have been conditioned by that barrier. According to collect El Periódico, the bridge will also shorten the distance between Cáceres and Lisbon by about 70 kilometers and half an hour. “It is a bridge that we need no matter what,” the mayor of Cedillo told the media. What remains pending. On the Spanish side, the access to the bridge was still pending bidding when Portugal already had the machines running. Both countries will coordinate the work through a Joint Technical Commission. The agreement between the Ministry and the Board has a maximum validity of four years, extendable. If the deadlines are met, Cedillo could have his bridge before the end of the decade.

The most famous bridge in the US recorded more than 2,000 suicides. Until in 2024 they found an “invisible” solution

When the golden gate Opened almost a century ago, it was celebrated as an architectural triumph of engineering and modernity. It happens that the history of many of the great works has had a second reading. Sometimes they have failed due to technical problemsand others have ended up marked by uses that no one foresaw. Over time, a bridge can become something very different from what its plans imagined. The bridge and its dark history. The Golden Gate Bridge, inaugurated in 1937 between San Francisco Bay and the Pacific, has been for decades one of the places most associated to suicide in the United Stateswith a rate of more than 2,000 jumps confirmed and a real figure surely higher because not all cases are seen nor all bodies are recovered. In 2006 there was one of the worst years, with at least 34 deathsand that was also the turning point in which relatives of victims, as Paul Mullerdecided that it was unacceptable to continue living with that routine of tragedies without a physical and effective response on the bridge itself. The barrier that changed destiny. The solution ended up being a deterrent system “invisible” installed along both sides of the bridge, one based on stainless steel cables of marine grade placed about six meters below the pedestrian walkways. It is not something that can be seen from afar or from normal traffic, but it is evident to those who look over the edge. The idea is simple and tremendous at the same time: if someone tries to jump, they fall on that structure, are injured or shocked, and the possibility of completing the fatal fall into the water is cut off. The barrier created to prevent suicides The effectiveness of the new impact. For many years the Golden Gate recorded an average of about 30 deaths annuallya figure that seemed entrenched and almost impossible to break. However, in 2024, with the facility entering its final phase and with adjustments still underway, the deaths they went down to eight. Last year, in 2025 and with the system already operating for twelve months, there were only four and there were no falls between June and December, a stretch that could be one of the longest without suicides on the bridge, although old records are not always complete. By the way, from the beginning of 2026 there is already a casewhich reminds us that there is no such thing as zero risk. That said, the general decline is so evident that even its promoters see it as clear proof of effectiveness and a mirror for the rest of the hanging architectures. Surveillance and intervention. The barrier does not act alone, because the bridge maintains an electronic surveillance system and a team of agents whose task is to detect and stop attempts before they occur. In the last year, 94 successful interventions were achieved, about half of what was normal before full installation, suggesting that the problem does not disappear suddenly. In fact, there are still people who come with the idea of ​​jumping, but now the margin of action is greater and death is no longer as immediate or as certain as it was for decades. Installation of anti-suicide barriers, February 2020 Against inertia and cost. The truth is that the installation of the barrier came after a very long road full of political blocks, doubts about aesthetics, discussions about price and debates about if it would really work. Already in 1939 it was recommended to raise the railings, but for decades measures were avoided while the death count rose from 500 to 1,000 and it continued to grow with chilling regularity. The organized pressure from family and professionals ended up crystallizing at the Bridge Rail Foundationand after years of paperwork the work started in 2018. The project also became very expensive, going from an estimate of 76 million dollars to a final cost of 224 million dollarsand even took longer to install than the bridge itself to build. The “invisible” barrier Why it saves lives. One of the central ideas is that reducing easy access to a lethal method works, even if it sounds too simple. A 1978 study by Richard Seiden, at the University of California at Berkeley, followed 515 people who had gone to the Golden Gate with the intention of jumping and were deterred, and concluded that 94% were still alive or had died of natural causes. This reinforces the idea that many suicidal crises are acute and not permanent, and that placing a specific obstacle at the exact moment can make the difference between dying and surviving. Bridges and the same problem. There is no doubt, the Golden Gate incident was not an isolated case, and there are other iconic bridges that have ended up with a similar reputation by becoming recurring scenes of suicides. In the United States, the royal gorge bridge next to Hoover Dam, or the Chesapeake Bay Bridgethey have had known histories and episodes that have fueled debates about surveillance and barriers. In Canada, the Bloor Viaduct in Toronto was for years one of the most problematic points until it was installed a great prevention structureand something similar happened in the United Kingdom with the Clifton Suspension Bridge in Bristol, where the combination of height, accessibility and symbolism forced action and reinforce early intervention. Also in Australia, the Sydney Harbor Bridge has been targeted of concern and initiatives preventive, and in Europe there are numerous cases on urban bridges and high-rise viaducts that share the same pattern: very busy and at the same time very exposed. The same idea is repeated in all of them, when a bridge becomes a known point, it is not just a problem of physical security, it is a social phenomenon that feeds on itself, and the more famous it is, the more important it becomes to cut that inertia before it becomes part of your identity. The legacy. The Golden Gate had been in operation for decades … Read more

The bridge with the largest steel span has completed its most difficult challenge. And it’s in China, of course.

There is not a month that does not release one mega constructionand in that area, China leads with an iron fist. Both due to the magnitude of his works, the technique used or the land they save with the structurethe Asian giant has become an example of perseverance when it comes to creating, above all, infrastructure that connects all its regions. After the highest bridge in the world, in the province of Chongqing, they are involved with another record-breaking bridge. One with the largest steel span in the world. Fenglai Daxi River Grand Bridge. As is often the case with these works, something that stands out as much as its magnitude is the construction time. In just three years, they have up a bridge in an extremely complex area. It clears two cliffs and the causeway will be 310 meters above the water surface. But more than because of the terrain, if it is news for something, it is because of the opening, that space between two columns. The total length of the bridge will be 1,136 meters when it is finished and the span is almost half of it: 580 meters that are suspended leaning on an arch-shaped structure made of steel. The height The arch in its central part is 116 meters and both the photos and videos show the complex lattice-type structure. Precision. More than a whim, it is necessary if you want to bridge that distance while looking for a bridge that can withstand both the weight and the possible tremors that are frequent in the region. To build the structure, engineers turned to BIM methodology (either Building Information Modeling) that simulates by computer all the processes of both the construction of the structure and its future maintenance. This is common, but essential in this lattice structure where many embedded components require an accuracy of less than a millimeter of deviation. On November 28, the team complete the union of each of the pieces weighing more than 300 tons that form that great puzzle of the lattice span, and now it remains to create the road that will consolidate the union between regions. Necessary. Because the Fenglai Daxi River Grand Bridge is not simply a feat of engineering: it is a catalyst for something China is aggressively pursuing. The country wants to carry out an economic and social transformation of the most challenging regions of its geography, and the Chongqing region falls into those plans as it has a large number of mountain ranges that have traditionally challenged communication with large centers. When completed, the bridge will be part of the Wu-Liang Expressway that will link the urban center of Chongqing with the Wulong district in approximately one hour, when with the current detour it takes approximately three hours, having to do a mountain route. And it is just one piece of a much more ambitious plan, which includes 52 construction projects, more than 1,200 kilometers of highways and a total investment of 155 billion yuan, about 19 billion euros. Megathings = tourism. Thus, the bridge will seek to become an element that will facilitate the flow of goods between the regions, but also of people with the objective of promoting tourism. Currently, in Wulong About 350,000 people live there and it has traditionally been a poor area due to the soil not being the best for farming and its natural isolation. However, since 1994, tourism has transformed it, especially since the Karst Geology National Park out including on the UNESCO World Heritage list in 2007. Now, Wulong aspire to become a global tourist destination, and this improvement in infrastructure seems key to achieving that goal. Furthermore, it is no longer just that China’s megaconstructions facilitate mobility: The buildings themselves are designed with the aspiration that they become points of interest. An example is Huajiang Grand Canyon Bridgean immense construction 625 meters above the level of the river that is used to cross from one side to the other, but It has a cafeteria and some adventure activities. Another is the Three Gorges Damwhich can not only move the axis of rotation of the Earthbut it also has a museum that documents the construction, an example of how the dam itself works and multiple observation points.

Italy snuck a bridge between Sicily and Calabria into NATO as “military spending.” Not even tanks can cross it

The hyperbolic idea of a mega suspension bridge record to unite the Italian peninsula with Sicily is something that the Romans already dreamed of. We are talking about an infrastructure that, if carried out, would become the largest suspension bridge on the planet. However, its chronicle as the driving force of rearmament in Europe is comparable to the project of underwater tunnel between Spain and North Africa. The old dream of the Strait. The ambition to link Sicily with the Italian peninsula by means of what would be the longest suspension bridge in the world reappeared at the center of the national debate not as a technical proposal, but as a head-on crash between political power and institutional control. Although the project It has been orbiting the imagination of different governments for decades, it was the combination of Matteo Salvini’s personal impulse and the political will of Giorgia Meloni’s executive that tried to reactivate it with an extraordinary sense of urgency. However, that speed caused the breakup: the Court of Accounts, constitutional guarantor of the control of public spending and compliance with national and European standards, rejected the file considering that the 2005 competition could not legally support a work that has tripled its estimated cost, that presents significant documentary gaps and that could violate essential rules of competition and environmental evaluation. Stand by. The decision made a few weeks ago, preventive and not definitiveexposed deep fissures in the management of the project, where political urgency prevailed over internal technical warnings from the Ministry of Transportation itself, which had requested more time to complete the documentation. The duel for two. The government’s reaction was immediate and furious. Meloni accused The judges were accused of overstepping their bounds and Salvini, who had turned the bridge into a symbol of his political survival, denounced a political gesture disguised as a technical judgment. They both had to moderate tone after recognizing that, although the Court of Auditors does not have the “final word”, its reservations are binding in the sense of raising the political responsibility of the executive: if the government decides to move forward without satisfying its objections, the Court will register the reservations and send them to Parliament, leaving an official record of the risks, including legal, budgetary and procedural ones. Continue without permissions. This warning is especially important given the possibility of future litigation promoted by groups opposed to the work. Still, the law allows the government go ahead even without the full endorsement of the institution, a path that Meloni and Salvini do not rule out, although aware that putting maximum pressure on the Court could open an institutional fracture that is difficult to manage and increase the likelihood that the courts will overthrow the project in later phases. The figures and the promises. The bridge 3.7 kilometers It is not just an infrastructure: it is a political symbol. Salvini presents it as a public work most important in the worldcapable of regenerating southern Italy, generating more than 36,000 jobs, stimulating economic growth of more than 23 billion euros and reducing crossing times across the Strait ten minutes away. But these arguments compete with other factors: its cost has escalated from the 3.8 billion expected in 2005. up to 13.5 billion current, and the Sicilian railway routes remain precarious. Furthermore, the local population asks before improvements in internal mobility that an iconic megaproject and the seismic risks of the Strait, one of the most active points in the Mediterranean, still lack a fully convincing technical response. For Salvini, however, abandoning the project would mean accepting a decline in his influence within the Italian right, especially at a time when Meloni dominates the political scene and his own bases are looking for evidence that he retains capacity. The technical fissures. The decision of the Court of Auditors was based on concrete elements: missing or poorly presented documentation, procedural shortcuts, inconsistencies between old figures and current projections, doubts about compliance with European procurement standards and an environmental file that, according to the judgesis based on claims of “imperative public interest” without the required technical support. The institution denounced that part of the essential documents They weren’t even pointed out. by the ministry, forcing the magistrates themselves to identify them. In parallel, the ministry’s technicians had warned Salvini months before that the precipitation could lead to exactly this scenario. The minister decided move forward anywayaware that delaying the process would have meant admitting that the work schedule set for the end of the year was impossible to meet. That political obstinacy is now turning against him, in the form of doubts about his ability to manage such a monumental project. The labyrinth of the contest. The most explosive element for the immediate future of the bridge is the question of the tender. Salvini opted to reactivate the contract awarded in 2005 to Eurolink consortiumled by Webuild and accompanied by companies from Spain and Japan, precisely to avoid a new contest. In 2012, when the project was paralyzed, the consortium demanded 700 million euros in compensation, which it will only withdraw if works resume. But the judges have pointed out that financial changes and uncertainty about the updated cost could force a new tender, which would delay the work for years, perhaps more than a decade. Environmental objections. The government tried to shield the project with a document that proclaimed reasons of public interest imperative to overcome environmental obstacles, but the Court of Accounts he replied that these justifications lack solid technical support and do not adequately detail the impact on extremely sensitive coastal and marine areas. Thus we arrive at the executive’s attempt to present the bridge as an infrastructure of strategic value. for NATO (arguing that it would facilitate rapid movement of troops in the central Mediterranean), an idea that was welcomed with skepticism and even irony: for regional experts, the bridge would be “at most a military objective,” not an operational tool. The use of international security as an … Read more

Spain no longer knows what to do with its surplus of renewables. So he is going to build a huge electric bridge with Ireland

Spain shines with sun and wind, but is drowning in its own green electricity. Solar and wind farms break generation recordsbut a good part of that energy is wasted due to lack of network, storage and connections with Europe. While the country operates in “reinforced mode”has found a possible solution to dispose of its renewable surplus. An electric bridge. On this path of releasing its excess energy, Spain has found in Ireland the best matches to connect. Irish Minister for Climate, Energy and Environment, Darragh O’Brien, advertisement After a meeting with the Spanish Secretary of State Joan Groizard, both countries are working on the construction of an underwater electrical interconnector between Ireland and Spain. Speaking to RTÉ NewsIrish Minister Darragh O’Brien announced that the project will seek to be co-financed with European funds and be completed in the mid-2030s. It will not be a minor project: the cable, he explained, will allow the buying and selling of electricity between both countries, balancing generation peaks. O’Brien acknowledged that, for now, “Spain is more likely to export energy to Ireland,” because the country usually has a surplus of renewable power that it cannot always take advantage of. We’re going to a wedding. The idea of ​​joining Spain and Ireland with an electric cable may sound eccentric, but it responds to continental logic: countries that produce green energy need to sell it, and those that are isolated need to receive it. In this context, our country is a clear example of the first group. The country has one of the largest renewable capacities in Europe —more than 40GW new since 2019—, but its level of international interconnection it barely reaches 2.8%well below the European target of 15% set for 2030. On the other hand, Ireland belongs to the second group. Its system depends almost entirely on the United Kingdom and France, and the country is, along with Spain and Finland, among the most exposed to blackouts due to lack of interconnections. according to a study by the consulting firm Ember. The analysis warns that 55% of the European electricity system has limits on importing electricity, which increases the risk of supply failures. How will the new cable work? It will be a high-voltage underwater interconnector (HVDC), the same system already used to move clean electricity over long distances between countries. The project is inspired by the Celtic Interconnectorthe Ireland-France link that will open in 2027, and will allow gigawatts of renewable energy to be transported under the Atlantic. There is still no closed route, but the Bay of Biscay appears as the most likely option: there it is already another cable advances between Spain and France, co-financed by the European Investment Bank. The political objective is clear: integrate the networks of the European periphery into an interconnected continental system, less vulnerable to blackouts and more efficient in the use of green energy. Furthermore, both countries recently led a meeting in Luxembourg of the “Friends of Renewables” group, together with 15 Member States and the European Commission. At that meeting, the new European Electricity Grids Package was presented, considered “one of the key pillars to facilitate affordable, safe and clean renewable energy.” Everything starts from the cables. The challenge is not only in producing more, but in transporting and storing energy. Spain invest only 30 cents in the network For every euro allocated to renewables, half of the European average. In this way, the cable with Ireland would fit into a map of projects that aims to break the energy isolation of the Iberian Peninsula. In addition to the Bay of Biscay link, are underway the Navarra–Landes and Aragón–Marsillón connections with France, a third interconnection with Morocco and new links between islands and the continent. If all these cables materialize, Spain will go from being “an energy island” to becoming an energy node between Europe and Africa, capable of exporting its renewable surpluses at competitive prices. The next great leap in European energy could start here: an electrical wire under the sea that connects the Spanish sun with Irish houses.

Italy is going to build the suspension bridge with the largest opening in the world. And they will load it to NATO’s budgets

The megaconstructions are the order of the day. We find each other Colossal projectssome that They make us crack an eyebrow thinking If necessary. However, few can boast of being the culmination of a work of centuries, or even millennia. Italy is close to getting it when approved A huge bridge that connect the continent with Sicily: the Messina bridge. The turn is that they have described it as something key to the NATO. So that? So that the bridge budget is included in the percentage of military spending that Italy must contribute. Historical dream. Sicily is a complicated territory. Isolated from the continent, it remains Italy and, although they have a very strong identity feelingthat isolation has led to some problems and difficulties throughout history. In it Roman empire I know proposed Unite the territory through the Strait of Messina with a peculiar plan: connect Calabria and Sicily using barges and barrels. It was ruled out for obvious reasons such as intense maritime traffic or its technical unfeasibility. In the Middle Ages, Charlemagne too study take actions to unite the territory and, in 1866, firmer plans were drawn to build a viaduct, but they were also discarded when considering that A tunnel would be more suitable. In whatever, it also ended in nothing and, during the following decades, the project of the bridge in the Strait was changing hands without success, maintaining the connection with the peninsula by ferry. Colossal. Throughout. Everything changed in 2023, when the new Giorgia Meloni government resurrected the plan. Contemplating an investment of more than 13,000 million euros, the bridge would mark a turning point in Italian, European and world architecture, depending on who we ask. The length will be about 3.7 kilometers with twin towers of 399 meters on both banks, a height of 72 meters above sea level so that large boats and capacity can pass and capacity to move A large number of vehicles. The three lanes in the direction offer a capacity for 6,000 vehicles per hour, and their two railways would allow a cadence of 200 trains per day. It is a transport barbarity to connect Sicily, but the only thing about this bridge will be the central opening: 3,300 meters that would set a new world record for a suspended vain. Necessary. The start of the works is scheduled for this same 2025 and its estimated completion by 2032. As we say, after many comings and goings, the project is already officially underwayas the Minister of Transportation and Infrastructure of Italy, Matteo Salvini, advertisement Last Wednesday. Finally, the cost will be 13,500 million euros and, as we read in New York TimesItalian minister and vice president, he is “absolutely proud of work.” Stating that “it will be an unprecedented public works in the world.” The justification of the bridge, as we read in Financial Timescomes from the side of the revitalization of Sicily. With this volume moved from the continent, the economy of one of the poorest regions of Italy can be promoted, where unemployment practically double The national rate: 13% compared to 6.5% of the rest of the country. But … necessary? The question is why, if a bridge between both territories was so important, something had been done. And, above all, why firm projects such as 2011 threw himself by land, arguing concerns about his price, about 5,000 million euros at that time and, in addition, about his real need. And it wasn’t the first time: Silvio Berlusconi He already proposed This project in 2005 for about 3.9 billion euros. Criticism. Many. There are few detractors of the bridge. This “unprecedented work in the world” faces opposition, environmentalists and even nature itself. The opposition, as New York Times states, considers that it is “an economic and social catastrophe” by diverting funds from other projects more necessary to build “a cathedral in the desert.” The animalists lo consider A disaster for local flora and fauna, as well as for a bird’s migration route. And when we say he has against nature, it is because those critics too comment that the area is prone to earthquakes that could make the bridge collapse. Even the ‘thing nostra’, the Sicilian mafia, said Be against the bridge in 2023. It has a trick. If you have so much against, if it is not clear that you will revitalize Sicily after a mastodontic investment, why do you go ahead with the project? During the NATO summit in June, Meloni declared that, due to the convulsive moment that is lived in several parts of the world, “there are many threats and hostile actors operating on the southern flank of the Atlantic Alliance.” In addition, he commented that “Russia projects more and more His presence in the Mediterranean” And this bridge would be a key piece, according to the Italian government, “in the context of NATO defense and security, facilitating the movement of the Italian and international armed forces in a context in which the Mediterranean is a geopolitically sensitive area.” And the trick? Well, like other NATO allies, Italy has beenOppromeded to increase its annual expenditure in defense Up to 5% of its GDP during the next decade, including 1.5% for strategic infrastructure. If the bridge is 13,500 million euros and include it in their proposals for “strategic infrastructure”, they would already be hitting a good bite to that 5% They must invest. Instead of armament or other elements, in a new bridge. Germany goes behind. “The Mestina Strait Bridge constitutes a fundamental infrastructure in relation to military mobility, taking into account the presence of important NATO bases in southern Italy,” they said in a report prepared last April, but Italy seems to be the only ones that will try to ‘put’ a renewal of infrastructure in that 5% of NATO. Germany, in a recent reporthas included in these defense budgets other 1 billion euros for the maintenance of ‘autobahn’, Your highway system. Forcing the machine. Returning to the Italian Bridge, and … Read more

We have found a “dark matter bridge” thanks to its predictions

Optical telescopes are instruments that allow us to see very distant objects thanks to the combination of lenses, objects that, through refraction, modify the path of light allowing us, among other things, to see objects unimaginably distant. However, there are other types of lenses that astronomers have used for a few years, gravitational lenses. An intergalactic “bridge”. Thanks to these lenses, a group of researchers He has discovered The remnants of an object that collided in the past with the galactic cluster of Perseus. Some remnants that have finally been detected thanks to the elusive dark matter. A resolved mystery. He Perseus cluster It is a group of galaxies located about 240 million light years from Earth. These clusters are formed from very high energy mergers, events that are among the most intense from the big Bang. Thanks to these mergers, Perseus has been accumulating An equivalent mass 600 billion the mass of our sun (or the equivalent to several hundred times the mass of our galaxy). Until now we believed that mergers were a thing of the past in this cluster, which was already in a kind of stable balance. However, more recent and detailed observations had shown clues of recent collisions that implied that Perseus He was not in the stability situation we thought. The mystery now, was to determine which object had recently collided with this Cluster And why we were not able to detect it. Now, it seems that we have resolved this enigma. Using lenses, otherwise. All thanks to the phenomenon we know as gravitational lens. This phenomenon, predicted by physicist Albert Einstein, is caused by gravity. This, far from “throwing” an object. It is common for astronomers to use this phenomenon as if it were an additional lens in a telescope, allowing to see beyond what in principle would be possible. In this new study, logic It has been the opposite: Use the bottom galaxies, to detect the lens, in this case, the one formed by dark matter. Display Dark matter bridge. Thus they found a huge cluster of dark matter, of an approximate mass of 200 billion solar masses and located around 1.4 million light years of the accumulation of Perseus. Between both structures a structure is extended that connects them, a “dark matter bridge” that the team considers direct evidence of the last collision. The collision would have occurred, according to team estimates, about 5,000 million years ago. “This is the piece that was missing and we were looking for,” James Jee, co -author of the study, stood out in a press release. From the Subaru telescope. The finding was made thanks to the observations made by the Subaru telescope of the National Astronomical Observatory of Japan, located in Mauna Kea, Hawaii. Specifically, the team resorted to the Sprime-Cam instrument of this 8.2 meter telescope. The details of the study were published In an article In the magazine Nature Astronomy. But is dark matter? Dark matter is one of the most popular enigmas of contemporary astrophysics. The generally accepted cosmological models are based on the existence of a “something” that interacts with “conventional” matter and energy through gravity. Dark matter is the name we give to what would otherwise be anomalies in astronomical observations. Still From the assumption about what There is this “something” And we are not, for example, using erroneous models, the nature of this matter remains one of the great mysteries of the cosmos.
