Unclogging Madrid is not an easy task, but the residents of Colmenar Viejo and Tres Cantos believe they have the solution: close the M-50

Unclogging Madrid seems like an impossible taskand perhaps it is, since it is one of the densest European capitals in terms of kilometers of highways and motorways. However, that does not prevent its residents from asking for better connections and ways to avoid the gigantic traffic jams that occur every day in the capital. One of the problems has to do with the M-50, and is that the residents of Colmenar Viejo and Tres Cantos have returned to demand the closure of this highway as an urgent measure to end the traffic jams that clog the main access roads to the north of Madrid every day. What happens with the M-50. The neighborhood platforms of both municipalities insist that “closing the M-50 is a definitive solution,” according to has collected Telemadrid. The situation is especially critical, since in some sections of the M-607, especially on the Colmenar highway, traffic density skyrockets every day, causing significant delays both at the entrances and exits to the capital. Neighbors claim that closing this road would relieve pressure on the A-1 and other vital axes in the northern part. What exactly do they propose? What is requested is not to physically close the highway, but to apply a model similar to that of the M-30 or M-40: restrict access to the most polluting vehicles to significantly reduce the volume of cars that circulate daily. This formula, they argue from Tres Cantos and Colmenar Viejo, would decongest the roads and provide a respite for thousands of drivers who use their vehicle as the only way to get to their jobs. Why the measure is rejected. The administrations have been rejecting the proposal for years for one main reason: if the M-50 is closed or restricted, it would further complicate mobility in Madrid. Many drivers currently use this route precisely to avoid the Low Emission Zones of the M-30 or the M-40. Hence there is fear of diverting traffic to other routes and that the alternatives end up becoming saturated. Other important implications are environmental in nature. And this closure would directly affect the Regional Park of the Cuenca Alta del Manzanares and Monte de El Pardo, key protected spaces in the Natura 2000 Network. The main impact would not be to “destroy” the park in its entirety, but rather high-value ecosystems would be fragmented, interrupting ecological corridors, affecting the habitats of protected species and altering natural processes such as aquifer recharge and the dynamics of the Manzanares River. Even the alternatives with tunnels carry significant risks (very invasive works, ventilation, impact on the subsoil and hydrology). Added to this is the indirect effect of adding more traffic and urbanization on an already sensitive stretch. What is being done in the meantime. To try to alleviate the problem, they are already underway the works of a third lane on the M-607specifically in the section between Tres Cantos and Colmenar Viejo. This measure seeks to reduce congestion in one of the busiest accesses, although residents maintain that it is a partial solution that does not address the underlying problem. Who should decide. According to neighborhood organizations, the competition to execute the closure corresponds to the central government. From the ‘Platform for the Completion of the M-50’ they denounce that the project has been delayed legislature after legislature due to lack of budget and political will, while their requests remain unaddressed.

In Tres Cantos they are analyzing the DNA of uncollected dog poop and fining the owners

The landscape, the species of trees, the flowers in the flowerbeds, the design of the paths or the games for children may vary, but in the parks of Spain (and many other countries) there are certain “basics” that are not usually missing: there are benches, there are fountains… and there is dog poopan annoying reminder that citizens do not always comply with the obligations that come with having pets. In recent years some city councils have tried to solve it creating DNA bases that allow them to locate the owners of the dogs and punish them if they do not take care of their feces. For a while, receiving one of those fines sounded like a distant threat, but in Spain there are already town councils passing from theory to practice. The last example Tres Cantos leaves it, in Madrid. What has happened? That the Tres Cantos City Council said goodbye to 2025 by activating its machinery to fine people who breaks its regulations. So far nothing out of the ordinary. The curious thing is the offense that is being pursued and above all how the City Council hunts down the offenders. What it has done is use the “canine DNA detection service” to fine those neighbors who ignore the excrement that their pets leave on sidewalks, parks and gardens. The ordinance makes it clear that people who walk pets through the municipality must collect “immediately” (and throw in the trash) the poop they leave in any area where pedestrians pass. Failure to do so is considered an infraction that, according to TeleMadrid specifiescarries fines of several hundred euros: between 300 and 600, depending on whether or not the offender is a repeat offender. Is it something new? Tres Cantos announced a year and a half ago his intention to create a “canine genetic census” to have the municipality’s dogs ‘registered’ and thus be able to identify excrement abandoned in the streets. In 2024 even launched a campaign baptized ‘I’m from Tres Cantos, it’s in my DNA’ in which it asked neighbors to register their pets in the following months. The idea was that people would take their animals to an authorized clinic to perform a simple test (basically taking a saliva sample) that would allow them to be registered. The procedure costs about 40 eurosbut the Consistory recalled that it is mandatory. Failure to do so also carries a penalty. The measure did not remain on paper and throughout the last few months the City Council has intensified their efforts to put it into practice, even with collection days of excrement. The surprise (and this is new) came on December 30, when the local government advertisement that the canine DNA system has already allowed him to identify “several owners” of dogs who do not pick up their pets’ feces. And he warned: “He will be punished” But… Is it that important? Yes it is. And not only because the measure wants to once and for all solve the problem of dog poop in cities. As remember from Tres Cantosthe canine registry is obtained in a “simple and harmless” way for the animal and serves many more purposes than sanctioning. “The genetic census is a reliable tool that protects animals, since it allows them to be located if they are lost, mistreated or abandoned, providing scientific certainty in possible judicial processes, claims and complaints,” claimed in July 2024 the Councilor for Public Health. In fact, the canine genetic census has already helped to resolve cases of puppy abandonment. Does it only happen in Tres Cantos? No. The idea of ​​canine DNA censuses has permeated more municipalities in Spain. In December 2024, Pipper on Tour estimated that 81 locations They already require pet owners to take them to clinics to have blood or saliva samples taken to carry out a census. In recent years the idea has attracted municipalities such as Malaga, Collado Villalba, Santa Eularia, Cornellà either Alcala de Henaresamong others. The latter in fact has a “canine CSI” for offenders who risk fines of between 300 and 3,000 euros. In its first year the program made it possible about 200 disciplinary proceedings, although many were directed at owners who still did not register their pets. In July Santa Eulària celebrated also that canine DNA has reduced fecal alerts by half.
