The original incident, which involved a truck, occurred on Wednesday afternoon, as reported by the Catalan Traffic Service. Although no serious injuries were reported, the impact slightly damaged the tunnel's infrastructure.
The decision was made to interrupt circulation specifically to execute these maintenance and repair tasks safely. The closure began at 7:45 AM on Thursday, January 8, causing significant traffic jams in the area.
Traffic disruptions lasted for at least two hours, affecting the morning commutes of drivers using this key route.
The C-16, known as the Eix del Llobregat, is a fundamental route connecting Central Catalonia, including Manresa, with the northern regions, such as Berguedà and Cerdanya, via the tunnel.
