Norway is making waves in the world of engineering with its ambitious plans to construct the Rogfast tunnel, set to be the longest and deepest underwater road tunnel in the world. This monumental project, with an estimated cost of $46 billion (£36 billion), is slated to open in 2033 and promises to revolutionize transportation in the region.
Record-Breaking Feat of Engineering
The Rogfast tunnel will span an impressive 16 miles (26 kilometers) and plunge to a depth of 1,300 feet (390 meters) beneath the sea. Once completed, it will surpass the current record-holder, Norway’s Lærdal Tunnel, which stretches 15 miles and connects the municipalities of Lærdal and Aurland in Vestland county.

The Rogfast project will link the municipalities of Randaberg and Bokn in Rogaland county, creating a vital connection along the E39 coastal highway. Currently, travelers rely on ferries to navigate this stretch, but the tunnel will eliminate this need, significantly cutting travel times and boosting convenience.
Transforming Travel Across Norway
Travel along the E39 highway, which stretches 680 miles between Kristiansand and Trondheim, currently takes 21 hours, largely due to ferry crossings. With the completion of the Rogfast tunnel, this journey will be shortened by 11 hours. Moreover, the tunnel will reduce the overall distance by 30 miles.
An estimated 6,000 vehicles are expected to utilize the tunnel daily. The commute between southern and northern Norway will become more manageable, with key cities such as Stavanger and Bergen becoming more accessible. The actual drive through the Rogfast tunnel will take approximately 35 minutes.
Motivations Beyond Travel
The construction of the Rogfast tunnel addresses not only travel efficiency but also logistical challenges. Project manager Oddvar Kaarmo highlighted the limitations of the existing ferry system, particularly during harsh winters when ferries at the Mortavika port often have to divert to other ports due to severe weather conditions.
“Once the tunnel is finished, we will not have to rely on good weather to keep the roads open,” Kaarmo stated. “About half a year after the last drill and blast, we have to deliver the project, so we have to get a lot of work done simultaneously. It’s more about logistics than tunneling.”
Funding and Costs
The Rogfast tunnel’s massive $46 billion budget is being primarily funded by the Norwegian government, which is covering around 40% of the costs. The remaining expenses will be offset through toll fees, with an estimated charge of £30 for vehicles using the tunnel.
While the financial investment is substantial, the project is expected to yield significant long-term benefits in terms of transportation efficiency, reduced travel times, and enhanced connectivity for both residents and tourists.
Legacy of the Lærdal Tunnel
Norway is no stranger to groundbreaking tunnels. The Lærdal Tunnel, which opened in 2000 at a cost of £90 million, has been a vital link between Oslo and Bergen, eliminating the need for ferries along its route. Visitors can also enjoy scenic fjord views in Flåm and explore the Snow Road between Aurlandsvangen and Lærdalsøyri, adding to the tunnel’s appeal as a tourist destination.
As a testament to Norway’s engineering prowess, the Lærdal Tunnel set the stage for the ambitious Rogfast project, demonstrating the transformative potential of undersea roadways.
