Oslofjord Tunnel repairs

摘要

The 7km subsea Oslofjord Tunnel in Norway was temporarily closed last month after a truck caught fire in the tunnel on May 5. Norwegian media reported that a 500m stretch was damaged - tunnel vault, cables, insulation and road surface. The tunnel is equipped with 25 evacuation rooms that can be sealed off from the main tunnel. Each room can provide pressurised space for up to 50 people while a fire is being fought. However, the latest incident has spurred the government to announce that a second tube will be built to hopefully reduce closures and improve safety.
