Norway to Build World's First Maritime Tunnel for Ships

Norway is embarking on a groundbreaking engineering project to construct the Stad Ship Tunnel, a maritime passage designed to bypass the treacherous waters off the Stad peninsula on its west coast. This region is notorious for its harsh weather, with over 100 days annually experiencing hurricane-force winds, sudden storms, and high waves, making it one of the most dangerous stretches for shipping.

The concept of a tunnel or alternative passage has been discussed since the 19th century, with Vikings themselves reportedly dragging their boats overland to avoid the hazardous seas. After years of political debate and escalating costs, the Norwegian Parliament initially supported the project in 2017, but progress stalled. A recent re-evaluation by the government in May 2026 has led to a new budget agreement, paving the way for construction to potentially begin in early 2027.

The Stad Ship Tunnel is both a groundbreaking engineering project and a practical solution to improve transport safety.

With an estimated cost of 8.6 billion Norwegian kroner (approximately 782 million euros), the Stad Ship Tunnel is set to become a unique feat of engineering. It will be 49 meters high and 36 meters wide, with a water depth of 12 meters, capable of handling vessels up to 16,000 gross tons. This capacity is sufficient for coastal express ships like Hurtigruten, significantly improving safety and reducing travel distance by 56 kilometers.

The construction itself presents a significant challenge, involving a "drill and blast" process through a thick layer of gneiss. Approximately three million cubic meters of rock will need to be excavated, with materials primarily supplied by sea due to inadequate local road infrastructure. The tunnel entrances, designed by the Norwegian firm Snøhetta, will feature rough rock walls to blend with the natural landscape, complemented by walkways and a new road bridge for viewing ships entering and exiting the passage.

We’re also informally part of the team, we’re absolutely on your side. I’ve already discovered the most hated word of the year: still.
