Barcelona’s metro network, although already extensive, is far from complete. Although there is currently only an expansion of the central trunk of L9/L10, which will link the North and South branches, the future holds a panorama of extensions and new stations that will completely transform subway transportation in the city and its surroundings by 2030.
The central trunk of the L9/L10 lines stands out as the most important infrastructure currently under construction. Although it has faced decades of delays, the project is expected to be completed in 2029.
In April 2022, work resumed to bore the remaining 4 kilometers of tunnel, marking a significant advance in the project.
The updated schedule in December 2020 suggests a three-phase opening. The first series, planned for 2026, will include Lesseps, Guinardó and Sagrera-TAV stations.
The second phase, in 2027, will incorporate the Camp Nou, Sarrià, Mandri, Sanllehy and Plaça Maragall stations, allowing the complete route.
Finally, between 2028 and 2029, the remaining stations of Campus Nord, Manuel Girona and Putxet will be opened. However, on paper, the La Ribera, Prat de la Riba and Montanya stations are still pending.
Major new station and expansion projects on the horizon
Apart from the central trunk of L9/L10, the Infrastructure Master Plan (PDI) for the period 2021-2030 reveals eight other extension projects that could change the face of the Barcelona metro.
-
L1 Fondo – Badalona Station
A long-standing demand of Badalona is the extension of the L1 on the Besòs side. This extension would include the stations of Montigalà, Lloreda | Sant Crist, Bufalà, Badalona Pompeu Fabra (with link to L2) and Estació de Badalona (with interchange for Rodalies). The project is scheduled to start construction in 2025 and be completed in 2031.
-
L1 Hospital de Bellvitge-El Prat Estació
This extension would take L1 from its current end at Hospital de Bellvitge to El Prat Estació, connecting with L9 and the Prat de Rodalies station. The informative study is expected to be drafted in 2025.
-
L2 Sant Antoni-Parc Logístic
A long-term project that would benefit Montjuïc and its surroundings. The extension of L2 would connect Sant Antoni with Parc Logístic, crossing key points such as Poble Sec, Montjuïc, Foc and Fira. Construction is expected beyond 2030.
-
L3 Zona Universitària – Sant Feliu de Llobregat
One of the most ambitious expansions, connecting Barcelona with four municipalities in the Baix Llobregat. It would include stations in Esplugues de Llobregat, Sant Just Desvern, Sant Joan Despí and Sant Feliu de Llobregat. The construction project is scheduled for completion in 2029.
-
L3 Trinitat Nova-Trinitat Vella
An apparently simple extension will connect the Trinitat Nova and Trinitat Vella neighborhoods with the green line. The construction project is expected to be drafted in 2026, but no construction start date is yet available.
