Barcelona's transport chiefs chart course for 2030: What officials and experts say about reshaping the city's mobility

Barcelona's transport planners are at a critical juncture, with senior officials and urban mobility experts offering divergent assessments of how the city should invest its €2.8 billion infrastructure budget over the next four years.

At the heart of the debate is the proposed extension of Metro Line 9 towards Sant Adrià, a project that transport authority TMB estimates will cost €890 million and serve 180,000 daily commuters by 2032. Municipal officials argue the project is essential for decongesting the L2 and L5 lines, which currently operate at 94 per cent capacity during peak hours—well above the 80 per cent threshold recommended by the European Union's urban mobility guidelines.

However, some urban planners from Barcelona's design think-tanks are questioning whether metro-centric investment remains the most efficient path forward. They point to the success of the newly expanded bus rapid transit corridor along Avenida Diagonal, which cost €156 million and now moves 42,000 passengers daily with significantly lower operating costs than underground rail expansion.

"The metro is iconic, but our city's geography and density patterns have shifted," said representatives from the Universitat Autònoma's Institute for Metropolitan Studies, which published a comprehensive mobility analysis last month. Their research suggests prioritising surface-level transit—bus lanes, tram extensions, and bike infrastructure—could achieve 70 per cent of the congestion relief at 40 per cent of the capital cost.

City transport councillors countered that surface solutions alone cannot handle the projected 12 per cent population increase expected by 2035, particularly in peripheral zones like Badalona and Santa Coloma de Gramenet.

The cycling sector has emerged as an unexpected voice in these debates. Officials from Barcelona's bicycle advocacy collective note that the city's cycling network has grown to 180 kilometres of dedicated lanes, yet usage plateaued at 6 per cent of commuter trips—significantly below Copenhagen's 32 per cent benchmark. They are lobbying for €85 million in dedicated funding to create safer north-south corridors through Eixample and Gràcia, arguing this represents untapped capacity.

The Catalan regional government, which co-finances major transport projects, has signalled that future funding will increasingly favour initiatives meeting zero-emission targets. This pressure is reshaping municipal priorities, with officials now emphasising electrification of the bus fleet—a €340 million undertaking—alongside traditional expansion plans.

As Barcelona prepares its final infrastructure proposals for EU approval by September, these competing voices suggest the city's transport future will likely blend old priorities with new imperatives, even as consensus remains elusive among the technical experts shaping the debate.
