Barcelona Metro L1 will face significant disruptions next summer as Transportes Metropolitanos de Barcelona (TMB) prepares for essential track renewal works between Mercat Nou and Santa Eulàlia.
The €10 million project involves comprehensive upgrades to both the catenary system and railway tracks along this crucial section of the city’s busiest metro line.
Transport authorities have strategically scheduled the complete closure for summer 2026, when passenger numbers traditionally decrease.

Consequently, this timing aims to minimise disruption for daily commuters and tourists alike. Furthermore, TMB has already initiated the tender process for the works, with bidding scheduled to close on December 5th.
Barcelona Metro L1 Upgrade Timeline and Details
Once the tender process concludes, TMB will finalise the exact dates and specific sections affected by the Barcelona Metro L1 closure. The works represent a significant investment in the city’s public transport infrastructure, focusing on the segment between Mercat Nou and Santa Eulàlia stations. This approach follows established patterns for major metro maintenance projects across European cities.
The comprehensive nature of these upgrades will involve replacing both overhead power systems and the actual railway tracks. Additionally, the project timing aligns with other major transport initiatives, including the Gran Via overhaul scheduled for 2026. Therefore, commuters should prepare for coordinated changes across Barcelona’s transport network.
Regular users of the Barcelona Metro L1 line should anticipate alternative transport arrangements during the summer 2026 closure period. Meanwhile, TMB is expected to announce detailed replacement bus services and travel advice well in advance of the works commencing. The authority typically provides comprehensive information through multiple channels to ensure passengers can plan their journeys effectively.
This essential maintenance programme underscores the ongoing commitment to modernising Barcelona’s public transport infrastructure. Moreover, it represents part of a broader strategy to enhance reliability and safety across the entire metro network. The Barcelona Metro L1 improvements will ultimately benefit the thousands of passengers who rely on this vital transport link daily.
