1,700 m above sea level: In the Linthal Project 2015 the inclined tunnel with an incline of 24 % compensates an altitude difference of 900 m in the high mountains of Switzerland.
A clever solution: What is normally a road tunnel turns into a storm water relief tunnel during floods. The storm water management and road tunnel in Malaysia is the answer to two challenges.
The Westerschelde tunnel ensured the first safe connection between the provinces of Zeeuwsch-Vlaanderen and Zuid-Beveland in the Netherlands. High water pressures in connection with loose soil posed new challenges to tunnel construction.
