Bypass Rockfall Protection – Safety in every passage

Bypass Rockfall Protection is an innovative, safe, and sustainable solution.

  • Patented, unique solution
  • Safe and uninterrupted travel, keeping communities connected
  • Maintenance-free
  • 100-year lifespan

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 rocks or debris is redirected away from the construction and the road, leaving it ready for travellers to pass through, despite new rockfalls.


Bypass Rockfall Protection 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 Rockfall Protection is designed for efficient installation. The prefabricated aluminium and steel modules are customized to fit the road section. It 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 Rockfall Protection 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.
