The intervention aims to replace the current ballast track with a new concrete slab infrastructure. In addition, the crossovers located between the Muntaner and Bonanova stations will be renewed.
To ensure user mobility, a replacement bus service will be provided, covering the affected route with stops at Gràcia, Sant Gervasi, Muntaner, Bonanova, Tres Torres, and Sarrià.
Regarding the rest of the network, S1 and S2 line trains connecting to the Vallès will maintain their regular schedules from Sarrià. However, the section between Gràcia and Plaça de Catalunya will undergo modifications, with frequency limited to 18 trains per hour in each direction. Lines L7 and L12 will remain unaffected.
The works will also impact road traffic on via Augusta between August 4 and 30. Lane restrictions and narrowing of the roadway are expected in the section between Madrazo and Ganduxer streets, as well as occasional diversions for the bike lane.
