The AP-7 is once again at the center of the debate on mobility in Catalonia. And just as share El Periódico, the Ministry of Transport and Sustainable Mobility has four projects underway to widen the highway with new lanes, a joint investment that exceeds 500 million euros. The works will affect almost a hundred kilometers spread between Vallès, Penedès and Terres de l’Ebre.
Why it is important. Since tolls were eliminated in 2021the AP-7 has ceased to be a highway designed primarily for long journeys and has become a road that also supports a good part of the daily traffic of the Barcelona metropolitan area, in addition to an intense passage of trucks of all kinds. This has led to almost daily traffic jams in the most densely populated sections and recurring collapses every summer.
In detail. The four projects are:
- Third lane between L’Hospitalet de l’Infant and Ampostajust over 38 kilometers. It is the most advanced, with the drafting of the project underway since 2023.
- Fourth lane between the B-23 and Martorellabout nine kilometers, in one of the main accesses to Barcelona, with an estimated cost of 94 million euros.
- Fourth lane between Sant Celoni and Montornès del Vallèsapproximately 30 kilometers.
- Fourth lane between Martorell and Vilafranca Centerabout 25 kilometers.
These last two are, as far as possible confirm ACN and El Periódico, which until now were not publicly known. Each project is in a different phase of processing, from preliminary studies to final drafting, so none of them yet have a closed execution date.
Between the lines. The problem is not just with private cars. Of the 41,000 vehicles that cross the border through La Jonquera on average every day, 15,000 are trucks, according to data of 2025 collected by El Periódico. The Ministry and the Generalitat agree that the railway should absorb a greater part of this freight traffic, but the lack of capacity of the railway network and intermodal terminals, together with a Mediterranean corridor still uncompleted, leaves the road as practically the only competitive option.
Meanwhile. Expanding lanes requires years of environmental and administrative procedures, so both administrations have chosen to also act where the highway loses fluidity without the need to build anything new. An agreement of 250 million euros Annually between the Ministry and the Generalitat will allow the remodeling of fifteen links (including Girona Nord and Sud, Maçanet de la Selva, La Roca del Vallès, Montmeló-Parets, the connection with the B-30 or Vilafranca del Penedès) to eliminate the so-called “braided”, the conflictive crossings between vehicles that enter and leave in a few meters and that generate a good part of the delays.
And now what. It is also still on the table limit truck overtaking in some sections, an option that the Servei Català de Trànsit is studying to reduce accidents while the works have not yet begun. In parallel, the debate has also resurfaced about whether it is appropriate to introduce a toll or a vignette on high-capacity roads, although both the central government and the Generalitat have ruled out recovering any means of payment for now.
The Minister of Territory, Housing, Ecological Transition, Sílvia Paneque, already claimed a few days ago in an interview with El Periódico to advance in these expansions to prevent the same image of collapse on the AP-7 from being repeated every summer.
