Norway Is Building the World’s Biggest Tunnel for Ships, and It’s Absolutely Massive

The world’s first tunnel for ships is to be built in Norway. The Stad Ship Tunnel, which is expected to open in 2023, will allow vessels to avoid a treacherous part of sea. Engineers will first have to blast 8m tonnes of rock to build the tunnel which will be able to accommodate cruise and freight ships

Norway has formally announced its plan to build the world’s largest tunnel for ships, paving the way for a gigantic 1.7-kilometre (1 mile) passageway to be dug underneath a rocky peninsula in the country’s north-west.

The Stad Ship Tunnel, which is expected to cost some US$312 million to complete, will enable cruise liners, freight ships, and smaller vessels to take an underground shortcut through the Stad peninsula – avoiding the rough winds and waters of the Stadhavet Sea, the most treacherous stretch of Norway’s coastline.
