Norway is constructing the world’s longest and deepest undersea road tunnel, Rogfast, designed to improve connectivity along the western coast and reduce reliance on ferries. Stretching 27 kilometers (17 miles) and reaching a maximum depth of 392 meters (1,286 feet) below sea level, the tunnel will significantly cut travel time between major cities, such as Bergen and Stavanger, by about 40 minutes. Construction began in 2018, paused in 2019 due to cost overruns, and resumed in 2021, with completion expected by 2033 at a cost of roughly $2.4 billion.
Rogfast will consist of two tubes with two lanes each, featuring a unique double roundabout 260 meters below sea level connecting to Kvitsøy island. Advanced technology, including spinning laser scanners and “digital twins,” ensures construction precision within a 5-centimeter margin, minimizing material waste and costs. The tunnel also incorporates safety measures such as longitudinal and shaft ventilation systems, real-time incident monitoring, and air quality controls. Part of the larger E39 ferry-free highway project, Rogfast will boost regional trade, employment, and access to services, while facilitating a more sustainable and integrated western coastal economy. Though shorter than some railway tunnels, Rogfast will surpass them in depth, marking a significant engineering achievement.
