Weather0°Friday 26. Still, there's something unusual about it, given how impressive it is: it's infrequently used and sees far less traffic than you'd actually expect from such a massive marvel of engineering and construction, and there's a reason why.

The World's Largest Underwater Tunnel Is Barely Being Used Today

Located in Japan, the world's largest underwater tunnel is barely being used.

The sparsely populated surrounding area further explains why the tunnel averages just 2,050 vehicles per day.

Yet, for those who traverse the tunnel, it’s an unforgettable experience. The illuminated rock chambers provide a surreal break from the otherwise dim, straight stretch of road, creating a sensory experience unlike any other.

After driving through the tunnel, visitors often pair the trip with a visit to the Borgund Stave Church.

The Lærdal Tunnel stands out for its scale, but it’s just one part of a system that enables Norwegians to navigate mountains and fjords easily.

The country’s obsession with tunnels stems from necessity. 2025, 16:19

The Lærdal Tunnel, at 24.5 km long, is an impressive feat of engineering connecting Lærdal and Aurland, eliminating the need for ferries and dangerous mountain routes between Oslo and Bergen.

With over 1,000 road tunnels crisscrossing the nation, Norway leads the world in tunneling innovation. Construction started in 1995 and the tunnel opened in 2000.

The tunnel is divided into four sections, separated by three large mountain caves. High air quality is achieved through ventilation and purification.

Laerdal Tunnel


Lærdal Tunnel is a 24.51-kilometre (15.23 mi) long road tunnel connecting Laerdal and Aurland
It is the longest road tunnel in the world, and carries two lanes of European Route E16, the main road between Oslo and Bergen.

Construction started in 1995, and the tunnel opened in 2000. Together, these stops turn a drive through the world’s longest road tunnel into a journey through Norway’s rich cultural and natural heritage.

  • The tunnel has a lighting system that simulates natural light at dawn.

    The remote location of the Lærdal Tunnel limits the daily traffic flow

    Despite its world-class design, the Lærdal Tunnel sees surprisingly low usage.

    Before these engineering marvels, harsh winters and geographic isolation meant months of seclusion for many communities. Its location, deep in the heart of Norway’s Sogn region, is far from major urban centers. With towering mountains and meandering coastlines, it is a marvel of natural beauty and engineering innovation.

    Among the many unique and interesting things you can only find in Norway, one of the most impressive is the Lærdal Tunnel, the world’s longest road tunnel.

    But with billions invested, why is this? The tunnel is divided into four sections, separated by large, brightly lit rock chambers. The tunnel eliminates the need for ferries or high mountain crossings between Oslo and Bergen, offering a year-round solution.

    To make the 15.23-mile journey less monotonous, designers incorporated unique features to enhance driver comfort and safety.

    It cost 1,082 million Norwegian krone, although unlike most tunnels in Norway was not subject to tolls.

  • The tunnel has a parking spot where you can stop and take pictures.
  • The central part of the tunnel is illuminated with white light, while the extensions are illuminated with blue-yellow lights. It cost 1,082 million Norwegian krone, although unlike most tunnels in Norway was not subject to tolls.

    The Lærdal Tunnel is an impressive piece of engineering.
