A lane closure slowed traffic on the Ronda Litoral (B-10) in Barcelona for kilometres on Tuesday morning, 21 October 2026. According to the Servei Català de Trànsit traffic was backed up for up to around seven kilometres at times. The causes were an accident in the early hours and scheduled maintenance work taking place at the same time near the Moll de la Fusta, which further reduced capacity.
The closure affected at least one lane. The tailbacks extended in the directions of Nus del Llobregat and Nus de la Trinitat. The Guàrdia Urbana managed traffic and recorded the accident, while the emergency medical services SEM were on standby to provide medical care. Recovery and clean-up work delayed the full reopening of the affected lane. No specific information about injuries was available that morning.
The overnight works on the B-10 near Moll de la Fusta have been announced by the authorities since mid-October and normally take place from Monday to Thursday. According to consistent local traffic reports, the combination of the accident aftermath and roadworks worsened congestion on the Ronda Litoral and diverted traffic onto city-centre routes.
The Servei Català de Trànsit provided real-time updates on conditions on the B-10 and warned of delays. City media picked up the notices. It was initially impossible to estimate when the disruption would end; this depended on the progress of the accident investigation, the removal of the vehicles involved and the course of the repair work.
The Ronda Litoral is one of the main transport arteries in the Barcelona metropolitan area. As previous incidents have shown, even the loss of a single lane on the B-10 can quickly affect the wider network. The latest incident confirms this vulnerability: during the morning rush hour, the combined restrictions had already led to significantly longer journey times along the coastal route and its access roads.
Facts at a glance: The incident occurred on 21 October 2026 in Barcelona; at least one lane of the Ronda Litoral (B-10) was closed; the Servei Català de Trànsit reported tailbacks of several kilometres. Quotations and assessments are based on official traffic notices and local traffic reports; no further claims were made about the duration or subsequent damage.
