Norway Building the World’s Longest and Deepest Subsea Road Tunnel

Norway’s Ambitious Project: Building the World’s Longest and Deepest Subsea Road Tunnel

Norway is currently constructing the Rogfast tunnel, set to become the longest and deepest subsea road tunnel in the world. Stretching 26.7 kilometres and reaching depths of up to 392 metres below sea level, Rogfast is a flagship project in the ambitious E39 Coastal Highway Route initiative, which aims to transform transportation along Norway’s rugged west coast.

Key Features of the Rogfast Tunnel:

• Length: 26.7 kilometres

• Depth: 392 metres below sea level

• Objective: Replace ferry crossings, reduce travel times, and enhance connectivity along the west coast

• Part of: The broader E39 Coastal Highway Route, aiming to create a ferry-free connection between Kristiansand and Trondheim

• Construction Timeline: Began in 2018, with completion expected by 2033

• Impact: A fixed link that will significantly cut travel time and improve mobility by replacing ferry services

The E39 Rogfast will not only set engineering records but also contribute to Norway’s goal of creating its first “climate+ road project”, setting new standards for sustainable infrastructure development.
