## Incident Reported at 7:28 AM

A traffic accident on the C-16 motorway near Sant Cugat del Vallès caused significant delays for commuters heading towards Barcelona on Tuesday 20th October 2026\. According to the Catalan Traffic Service, the incident was reported at 7:28 AM and forced the closure of one lane in the eastbound direction between kilometres 11 and 14\. The disruption occurred during the morning rush hour, affecting drivers using this key route into the city. The C-16, a major road connecting Barcelona with towns in the Vallès region including Terrassa and Manresa, passes through the Túnels de Vallvidrera in this section, a known bottleneck during peak times.

## Traffic Resumes by 9 AM

By shortly after 9 AM, the Catalan Traffic Service confirmed that traffic had returned to normal following the resolution of the incident. Emergency crews cleared the scene, allowing all lanes to reopen. Drivers were advised to allow extra travel time during the disruption. The Túnels de Vallvidrera are monitored by safety systems, following past municipal concerns over emergency access and response times, as noted in a 2019 Ajuntament de Sant Cugat report on tunnel safety.
