Barcelona and Sant Adrià seal alliance to manage joint projects

Published on June 20, 2026 | Translated from Spanish

The Barcelona City Council has signed an alliance with Sant Adrià de Besòs to coordinate mobility, housing, and public space projects that affect both cities. This cooperation aims to solve shared problems more efficiently, improving services and works for the residents of both localities.

A technical plan to connect infrastructure and urban data 🚇

The alliance involves synchronizing transport systems, such as buses and bike lanes, and sharing traffic data to reduce congestion. In housing, construction and renovation criteria will be unified in border areas. For public spaces, parks and sidewalks will be designed with visual and functional continuity. All of this requires common digital platforms to manage incidents and works without duplicating efforts.

Two mayors, one traffic light, and a lot of bureaucracy 🚦

Now, residents on the city border won't know if the pedestrian crossing is from Barcelona or Sant Adrià. The good thing is that if there is construction work, two municipal teams will no longer need to argue over who puts out the cones. The bad thing: coordination meetings will last twice as long, but at least they will serve to decide which side of the park bench each city council paints.
