World’s Longest Underwater ‘Megatunnel’ To Cut 21-Hour Coastal Drive Into Half

Human beings have made significant advancements in infrastructure, particularly in constructing long tunnels. One notable example is the tunnel between Lærdal and Aurland in Norway, which is 24.51 kilometres long. Another impressive tunnel is the Yamate Tunnel in Tokyo, Japan, which spans 18.2 kilometres. In New York State, the Delaware Aqueduct stands out at 137 kilometres long. Norway is currently building the world's longest and deepest road tunnel, The Rogfast. Expected to open in 2033, this monumental project will stretch 16 miles and reach depths of 1,300 feet underwater. It will connect the municipalities of Randaberg and Bokn in Rogaland county, Norway.

Making Travel Accessible

With a projected cost of $46 billion, this engineering marvel aims to significantly improve the commute between Norway's southern and northern regions. Upon completion, the Rogfast tunnel will revolutionise Norway’s infrastructure and reinforce its status as a pioneer in innovative engineering and sustainable travel. With an estimated 6,000 vehicles set to traverse the tunnel daily, commutes to key cities like Stavanger and Bergen will become significantly smoother and more efficient, greatly enhancing daily travel experiences for everyone.

Open During All Weather

This groundbreaking project will not only set a new standard in undersea construction but also provide a reliable and efficient alternative to ferries, making Norway’s breathtaking routes more accessible than ever before for travellers. The tunnel is designed to enhance transportation during inclement weather, as the port at Mortavika is vulnerable, and ferries are often diverted in winter due to adverse conditions. Once the tunnel is completed, the weather will no longer impact travel, ensuring the route remains open.

The Rogfast tunnel is poised to transform transportation between southern and northern Norway by doing away with the need for ferry rides and significantly reducing commuting times along the E39 coastal highway. This tunnel will save travellers up to 11 hours by shortening the 680-mile journey from Kristiansand to Trondheim by 30 miles. Currently, this trip takes about 21 hours. The tunnel is designed to accommodate 6,000 vehicles daily, facilitating more seamless connections to major cities. The underwater journey will only take 35 minutes. A proposed toll of £30 will be charged to users.
