The southern entrance to the A5 underground is already 80% excavated, and there is a culprit that has speeded up the work: the soil
Allow me, if you don’t mind, to use an expression that I have been wanting to use for a long time: there is already light in the tunnel. That’s right, then the burial of the A5 Move against the clock to meet deadlines. And the goal is to open traffic in November. The southern tunnel of the Extremadura highway has already exceeded four fifths of its route under Madrid. There is less left, largely due to the technical innovations that have made it possible. The largest work in Madrid right now. The burial of the A-5 is, today, the largest infrastructure under construction of the capital. Under the streets that connect Madrid with the exit to Extremadura, two tunnel boring machines work in parallel to bury one of the historic entrances to the city and thus free up surface space for urban use. Where is each tunnel. The work runs in two independent galleries. The southern tunnel, through which vehicles entering Madrid will circulate, has been excavated for approximately 80% of its length. The northern tunnel, the exit, is advancing at a slower pace and has completed about half of the route. Although the asphalt has not yet been laid, the interior appearance of the most advanced gallery already allows a fairly clear idea of what the final infrastructure will look like, according to transfer to Telemadrid the technical teams that supervise the work. The key to acceleration: the ground. As the media points out, a new construction system applied to the tunnel floor has made it possible to speed up both the excavation and the consolidation of the infrastructure. For this reason, and because of the work that is being put into the work every day, it has been possible to reach 80% without major delays, maintaining the schedule. 14 emergency exits. Parallel to the main gallery, the work includes the construction of 14 emergency exits, one every approximately 200 meters. Each of them is accompanied by technical rooms where the systems necessary for the operation of the tunnel will be housed, including geothermal installations that will improve its energy efficiency. Jump to the surface. Starting in September is planned that the works also extend abroad, with urbanization actions in the area around the A-5. The idea in this phase will be to definitively integrate the infrastructure into the surface, with the aim of reducing traffic outside and taking advantage of the area for new public spaces. November, the date marked on the calendar. With the tunnel boring machines still in operation, the goal is for vehicles to be able to travel through the new tunnel before the end of the year. November is the date currently managed by those responsible for the work. So we just have to wait a few more months to call it a day. one of the heaviest works of these years in the capital.
