Flexible traffic routing

Lowerable crash barriers

Hydraulically lowerable crash barriers for quick and safe rerouting of traffic.

In a very short time, lowerable crash barriers can alleviate the congestion and traffic chaos that is caused when one lane of a tunnel is closed. If necessary, they can be lowered within minutes and can also facilitate the implementation of construction, maintenance and cleaning measures. 

In the lowered state, the crash barriers are flush with the ground and can be driven over by heavy vehicles, while robust construction permits operation in all weathers.
