Sanchinarro is one of the most desirable neighborhoods to live in on the outskirts of Madrid, so much so that it was the place where rents rose the most in 2025. But something that its newcomers do not count on is a traffic problem that has been dragging on for months.
The bridge connecting Sanchinarro with the M-40 has become a symbol of neighborhood frustration: a project announced as a quick fix on the deck, dismantled in November “for a few days” and now turned into a landscape of fences, immobile machinery, and permanent detours.
The Ministry of Transport declared the work an emergency project to repair and replace the overpass deck after detecting structural damage that forced traffic to be cut off on the structure and the M-40 to be closed at kilometer 2 on several weekends in November. The plan was clear: dismantle the damaged deck in two phases, rehabilitate the piers and abutments, and then install a new structure, concentrating the most severe closures between November 8 and 16 to minimize the impact on traffic. However, once the dismantling work had been carried out and the highway reopened, the area around the bridge was left looking like a kind of “ghost construction site”: closed accesses, a closed tunnel, and a building site where, according to local residents, there is hardly any activity.
Neighborhood complaints about lack of information
For the neighborhood, the “mystery” is not so much technical as it is communicative; it is already known that the old deck was removed and that the structure needs extensive rehabilitation, but there is no detailed public schedule explaining when the new deck will be installed or at what exact point the work is.
Meanwhile, Sanchinarro is trapped in a traffic jam. Direct access to the northbound M-40 has been closed since October, forcing vehicles to use alternative routes via Niceto Alcalá Zamora, Santo Domingo de la Calzada, and Camino de Santiago, and any incident during rush hour causes gridlock at the neighborhood’s exits.
Neighborhood associations and users of the area complain that, after the initial deployment of cranes and spectacular closures on the M-40, the work has entered an opaque phase, with hardly any machinery working in sight and no clear explanations for the delays, beyond generic references to the technical complexity of the intervention. In practice, Sanchinarro’s connection to the rest of the city now depends on longer and more congested routes, while the bridge remains a desert of concrete and rebar that reminds drivers every day of the promise to “stop for only two weeks” that was never fulfilled.
