Malta Failed, Norway Builds: The World’s Longest and Deepest Tunnel

The future of traveling across Norway’s rugged coastline is about to be revolutionized. Imagine cutting a 13-hour drive down to just half an hour, all while cruising beneath the ocean waves. That’s the promise behind Rogfast, a stunning new tunnel project set to become the longest and deepest underwater road tunnel on the planet.

Instead of navigating the current coastal highway, which is long, winding, and interrupted by ferry rides, drivers will soon speed through a 17-mile tunnel that connects multiple cities seamlessly. This bold endeavor marks a new chapter for transportation in Scandinavia and showcases incredible feats of engineering.

How the new tunnel changes travel in Norway

Currently, Norway’s coastal highway, known as the E39, sprawls over approximately 677 miles (1,090 kilometers) and stretches from the northern city of Trondheim all the way down to Kristiansand in the south. Completing the entire journey takes about 21 hours, mainly because travelers must board ferries seven different times to cross fjords along the route.

With Rogfast, this time will be slashed dramatically. The new underwater tunnel will connect the districts of Randaberg and Bokn by burrowing 17 miles beneath a fjord, eliminating the need for any ferry detours. Once finished, drivers can cut nearly 13 hours off the trip, covering what once took almost a full day in just around 35 minutes.

This improvement isn’t just about speed; it’s a lifeline for better connectivity. The tunnel will directly link six cities in Norway, encouraging smoother, more reliable travel without the unpredictable delays often caused by weather or ferry schedules.

Impressive scale and innovative design features

Rogfast stands out not only for its length but also for its depth. The tunnel will plunge nearly 1,312 feet (400 meters) below sea level, earning its spot as the deepest underwater tunnel in the world designed for road traffic. Its four lanes—two for each direction—mean drivers won’t have to worry about congestion slowing their way.

Construction of this ambitious project began in 2018. However, progress slowed due to challenges like the global pandemic and the complex engineering required to carve through solid rock beneath the sea. Despite the obstacles, the goal is to have the tunnel ready by 2033.

The price tag is equally bold, with an estimated cost of nearly $2 billion (about 1.9 billion euros). The funding comes from a mix of government support and tolls—drivers can expect to pay roughly 30 pounds per crossing. While this might sound steep, the benefits in travel efficiency and reliability are expected to far outweigh the cost.

Why the tunnel is a breakthrough for safety and logistics

Anyone who’s ever traveled along Norway’s coast knows the frustration of winter weather shutting down ferry service. Strong storms and rough seas often delay or even cancel crossings, forcing travelers to wait hours or find alternative routes. This unpredictability affects daily commutes, freight deliveries, and tourism.

Rogfast tackles this problem head-on by moving traffic beneath the water, where weather won’t disrupt travel. As Oddvar Kaarmo, the project director, points out, this uninterrupted route will be a game changer for Norway’s transportation network.

Building such a tunnel beneath the seabed presents massive engineering challenges. The construction team has to handle complex rock formations underwater while coordinating multiple tasks simultaneously under tight timelines. It’s a testament to modern technology and innovation in civil engineering.

The tunnel’s impact on Norwegian daily life and economy

Beyond transforming long-distance travel, Rogfast will reshape daily life in Norway’s coastal communities. Faster routes mean goods get to market quicker, local businesses can thrive, and people have more time for what matters.

Tourism may also see a boost as visitors enjoy easier access to scenic areas without ferry hassles. Driving under the sea for a short, safe trip instead of waiting hours to board a ferry sounds like a dream for many.

Speaking from experience, long ferry waits during road trips can be exhausting and can feel like lost time you’ll never get back. I remember a trip where a ferry delay stretched a scenic drive into an almost full day of waiting. A tunnel like Rogfast promises to eliminate those frustrations with a smooth, uninterrupted path.

Norway’s bold step to lead the world in submarine road tunnels will likely inspire future projects in other countries with challenging coastlines.
