Project Description

Line 3 (Green line) is the oldest and second busiest line of the Barcelona subway network. Since the line first opened in 1924, it has been progressively extended to adapt to the growing urban area. One of these extensions was completed in 2001, between the stations Mundet to Canyelles, in the north of the city.    

Pedelta was responsible for the detailed design of 2.5 km of subway extension, including three stations.

Design/Construction Approach

The cut and cover method was used in most of the project, either using RC slabs or tri-articulated RC vaults, depending on the segment. The distance between cantilever walls varies between 8.4 and 20.5 meters while the maximum height reaches up to 24.6 meters. In the scope of the design was to minimise the footprint and interference with existing traffic on adjacent streets and provide a minimum cost. The project included the construction of some other structures to keep existing utilities. A refined structural analysis was carried out to limit interferences with nearby buildings and with the Ronda de Dalt, a major arterial road of Barcelona.
