The bottleneck is caused by a closed lane

The accident forces the closure of a lane and this reduces the capacity to handle the usual volume of vehicles. With one less lane available, traffic slows down and queues form stretching up to 1.5 km. Drivers must prepare for slower movement and possible waits.

Tarragona direction: the most affected route

The Tarragona direction is the most affected by this incident, which especially impacts trips towards the Costa Daurada or the city itself. Regular AP-7 users should take this information into account to adjust schedules or seek alternative routes.
