Total closure on Diputació: detours and key traffic changes in Barcelona
The closure on Diputació due to the L8 works is changing mobility, with new detours towards Vilamarí and Plaça Espanya and staff providing information on alternatives.
From 12 January, Diputació in Barcelona will be closed to traffic between Llançà y Tarragona due to the works to extend FGC L8. The closure, which will last for months, requires changes to usual routes and affects both drivers and emergency services.
Private vehicles must detour via Entença y Calàbria towards Aragó y Tarragona to access Plaça Espanya. Only residents and emergency services will be allowed to drive on Llançà, while visitors to the shopping centre will have restricted access at the same point.
From 26 January, the expansion of the launch shaft on Gran Via will reach Vilamarí, bringing new restrictions. Vilamarí will have a mandatory turn onto Gran Via towards Besòs, except for buses, emergency vehicles, and residents. Crossing Gran Via or turning towards Plaça Espanya will not be allowed. In addition, the stretch between Sepúlveda y Gran Via will become a dead end and will be two-way.
The Departament de Territori explains that these changes are due to the start of preparatory work to install the tunnel boring machine on Gran Via. The restrictions will remain in place until the tunnel excavation is complete. In February, construction will begin on an underground gallery connecting the excavation area under Gran Via with the logistics area in Joan Miró park. This gallery will be used to transport the soil removed during the works.
At the same time, work is progressing on building an acoustic enclosure to provide protection during the tunnel excavation, which is scheduled for the summer. In Joan Miró park, the pit and acoustic protections for the logistics area are being finalised, as well as the structures for the soil conveyor belt. In February, assembly of the microtunnelling machine and excavation of the gallery will begin.
The City Council has deployed a team of information staff who, during January, will explain the changes and mobility alternatives on the street. In the first half of the month, they will be on Diputació; in the second half, they will focus on Vilamarí.
