The closure, confirmed by the Traffic Central, is expected to last approximately two hours as indicated by traffic alerts on the Norwegian Public Roads Administration's website. Emergency services, including police and fire department, are swiftly responding to the incident, which took place on the Hurum side of the tunnel.

According to police operative leader Gisle Lindheim Sveen, there appears to be no signs of an active fire despite the smoke. Recovery operations for the stranded truck have been initiated, ensuring that the area is safe for both emergency responders and motorists. This incident is significant as it highlights the ongoing challenges associated with road safety and emergency management in tunnel environments.

This double closure reinforces the importance of timely communication about traffic conditions for the safety and convenience of motorists traveling through the area.
