A new study has highlighted Barcelona’s most dangerous cycling roads, revealing a sustained increase in accidents involving cyclists across Catalonia. The report, published by the Royal Automobile Club of Catalonia (RACC), identifies the ten road sections with the highest concentration of bicycle accidents. Significantly, seven of these dangerous routes are located in Barcelona province.
While the latest figures show 357 bicycle accidents recorded, a 7% drop from the previous year, the report’s analysis of the 2022-2024 period indicates an overall upward trend. Consequently, accident numbers now surpass pre-pandemic levels. These figures reflect a worrying regional pattern, as separate data shows that Catalan road deaths increased in 2025. The study points to cyclist vulnerability and inadequate road adaptation as key factors behind serious incident concentrations.

Dangerous Cycling Roads Barcelona: Top Accident Blackspots
For the second consecutive year, the BV-5001 between Martorelles and Vilanova del Vallès has been named the most hazardous route. According to the RACC, cyclists are involved in 60% of all serious accidents on this particular stretch. The persistence of these danger zones remains a key concern, with six of the top ten blackspots reappearing from the previous year’s ranking.
Other high-risk roads in the Barcelona area include the N-II near Mataró, the B-210 between Viladecans and Gavà, the C-31C between Sant Boi de Llobregat and El Prat, and the B-510 between Argentona and Llinars del Vallès. Notably, all serious accidents on the B-510 involved cyclists. The report notes that most incidents are linked to recreational bicycle use.
Infrastructure Improvements and Safety Awareness for Barcelona’s Cycling Roads
The RACC study attributes the rising accident trend to increasingly intense coexistence between urban, interurban, and bicycle traffic on roads originally designed for cars and lorries. Ramon Lamiel, director general of the Servei Català del Trànsit, noted during the presentation that “the bike has been incorporated into mobility” more significantly since the pandemic. This shift is not isolated to cycling, as the city also reported record public transport usage during the same period.
In response, the Generalitat is considering installing new warning signs to alert drivers to cyclist presence in high-risk areas. Meanwhile, other traffic calming measures appear effective, as recent data shows that speed camera fines decreased in Barcelona. The report, published as part of the International Road Assessment Programme (iRAP), urges authorities to adapt road infrastructure to growing bicycle use. Therefore, targeted improvements are essential on sections where serious accidents repeatedly occur.
