Building the world’s longest and deepest road tunnel
Shaping connection with Hexagon’s technologies.
The problem
Norway's landscape is notoriously difficult to navigate for commuters and industry transport
Hexagon’s solution
Skanska is using Hexagon's measurement technologies to build the world's longest and deepest road tunnel to 5 centimetres accuracy
The outcome
Project Rogfast will help connect local communities and cut travel time by half between major cities
Connecting Norway
Skanska, Norway’s largest civil contractor, is building Project Rogfast, a 27-kilometre subsea tunnel that will be the world’s longest and deepest road tunnel.
The tunnel, running 392 metres below sea level, will connect Stavanger, Haugesund, and Bergen, helping cut travel time by 50% and connect the oil and gas industry.
“Traveling in Norway takes time. Efficient roads like Rogfast are crucial for progress.”
Trond Valeur, Vice President, Skanska Norway
Achieving maximum accuracy
Skanska is drilling and blasting a major part of the tunnel, meeting another team in the middle with an accuracy of 5 centimetres or less.
“It’s like two people sitting across from each other, blindfolded, trying to touch fingers. Hexagon technology makes it possible.”
Rolf Christian Kværnæs, Head of Geomatics, Skanska Norway
Reduced time, cost, and emissions
Hexagon ensures Skanska gets it right the first time, reducing waste and lowering the project's carbon footprint. Just 10 centimetres off in drilling and blasting equal 1-2 extra truckloads per session.
Surveyors use Hexagon tools like total stations and laser scanners to measure efficiently and safely in hazardous underground conditions.
“If we are ten centimetres out of a lane, it will build up all the way down. Our surveyors use Hexagon’s technology every day to do work right the first time. It’s not sustainable or economical to do it twice.”
Anne Brit Moen, Project Manager, Skanska Norway
Bridging distances, driving progress
Rogfast will reduce reliance on ferries, making travel faster and independent of weather.
The tunnel strengthens connections between communities and Norway’s vital oil and gas hubs, driving economic growth.
