World's first full-size ship tunnel will be just one mile long - and cost £671m

The Norwegian government has approved the ambitious project of the Stad Ship Tunnel, the world's first full-scale underwater tunnel for ships, stretching a mile along the country's west coast at a cost of £671 million. This groundbreaking initiative aims to alleviate congestion in coastal shipping routes and boost maritime efficiency, marking a significant leap in marine engineering. While the tunnel's modest length may seem minor, its success could pave the way for future large-scale underwater projects, potentially transforming global shipping logistics.
