Gofrixty [07 August 2025] – The Norwegians are making a name for themselves as leaders in innovative transportation, forging ahead with the construction of the world’s longest and deepest subsea road tunnel—the Rogfast Tunnel. The construction is one of the country´s largest infrastructure projects as it looks to upgrade its road network and provide better connectivity between the west coast ports.
The Rogfast Tunnel will run 27 km (16.8 miles) under the sea and link Stavanger with Bergen. What is truly remarkable about it however is the depth- descending some 392 meters (1,286 ft) beneath sea level. This depth smashes global records and represents an engineering challenge of the highest order. However, Norway has resolved the challenges by using new technology and experience.
To bore through underwater rocks and soil, engineers are employing rock-blasting methods alongside new tunnel boring machines equipped with enhanced safety systems. They are planning to install ventilators, lights, fire safety smart systems and traffic control intervention from the cloud as well which will help any driver safe. When it is completed, the tunnel will have two-way traffic and thousands of vehicles could travel through it each day.
