Barcelona accelerates 24 urban projects and 18 resurfacing works this summer. Major streets and public transport will face closures and detours. The city aims to complete critical upgrades before the next municipal elections.
Barcelona is entering a decisive summer as the city government pushes to complete or advance its most significant urban projects before the next municipal elections. With 24 major interventions and 18 resurfacing operations scheduled, residents and commuters will face notable disruptions across key streets and public transport lines.
The works will impact traffic, tram, metro, and Ferrocarrils de la Generalitat services, with the city concentrating construction during the school holidays to minimize daily mobility issues. Among the headline projects are the renewal of Balmes street, the transformation of La Rambla, and the visible start of the Ronda de Dalt coverage between avenida de Vallcarca and paseo de la Vall d’Hebron.
On Balmes, the final phase of a 2024 renovation will see over 15,000 square meters upgraded. The entire roadway between ronda General Mitre and Via Augusta will be resurfaced on July 11 and 12, requiring a full closure and rerouting of traffic via Riera de Cassoles. Bus lines V15, 198, 27, and D40 will also be diverted. Sidewalk finishing works will continue until the end of July.
Meridiana avenue will undergo resurfacing between Felip II and Fabra i Puig, with inbound lanes affected from July 31 to August 7 and outbound lanes from August 8 to 14. At least one lane will remain open in each direction, but several bus lines, including 96, 126, V27, V29, H8, and shuttles for L9 and L10, will see changes. Interurban services will also be impacted.
La Rambla’s high-profile redevelopment is set to continue, with completion targeted for February 2027. This summer, the city will focus on the Gòtic side, aiming to open new sections of the promenade. Current work is centered on the Raval roadway and various parts of the central walkway, with the goal of enabling the reopening of the southbound lane in the coming months.
The Ronda de Dalt coverage project, launched in 2024, will enter a visible stage this August. Over 16,000 square meters of new public space are planned above the infrastructure between avenida Vallcarca and paseo de la Vall d’Hebron. For three weeks, the slow lane will be closed to install lighting, communications, and safety systems for the future tunnel. Nighttime closures in both directions and phased disruptions between avenida Vallcarca and avenida Jordà are expected.
Transport infrastructure will also see significant maintenance and expansion. The extension of Ferrocarrils de la Generalitat’s line 8 around plaza España will continue to affect the area from June 25 to September 7. The tunnel excavation for L8 is due to finish by year-end, though further works will follow.
Metro line 1 will undergo track renewal, suspending service between Hospital de Bellvitge and Plaça de Sants from July 17 to August 28. Additional works will proceed at the Catalunya interchange and on lines L9 and L10 Norte. Tram services T4, T5, and T6 will be interrupted between July 3 and September 13 due to ongoing construction near Glòries and Gran Via.
Barcelona’s approach reflects a broader trend in Spanish cities to concentrate disruptive works during periods of lower mobility, aiming to balance urban renewal with daily life. The city’s population of over 1.6 million relies heavily on public transport, making coordination between agencies critical during such large-scale interventions. As the city prepares for the next election cycle, the completion of these projects is set to shape both mobility and the urban landscape for years to come.
