Keep the road open during and after a rockfall
When the rockfall hits Bypass Sikkerhetstunnel, the energy is absorbed within just 1/10 of a second. The debris is redirected away from the construction and the road, leaving Bypass Sikkerhetstunnel ready for travellers to pass through, and new rockfalls.
Bypass Sikkerhetstunnel features an open-side design, providing natural ventilation and emergency exits. The risk of smoke and gas accumulation is minimal.
Efficient installation keeps communities connected
Bypass Sikkerhetstunnel is designed for efficient installation. The prefabricated aluminium and steel modules are customized to fit the road section. Bypass Sikkerhetsunnel is available in 4- to 8-meter modules, depending on the road width. Due to the smooth installation process, infrastructure can remain intact with one lane open.
Since the structure is mounted directly onto the existing roadway, there is very limited negative impact on the surrounding nature. Additionally, the structure can easily be dismantled and reused elsewhere, offering a flexible and sustainable solution.
Well-established technology at its core
The principle behind Bypass Sikkerhetstunnel is the same as a vehicle placed upright. The safe, green zone is surrounded by a solid and secure framework that absorbs impact. The green zone itself can withstand the full force of a rockfall without collapsing.
The overhead structure (red zone) is our patented technology. It is unique because it absorbs the impact of the rockfall and then redirects the debris away from both the structure and the road.
Multiple use-cases
Bypass Sikkerhetstunnel is flexible, and we are developing several alternative designs. Here are some of them:
