Height Control
The tunnel operation office controls traffic with 72 visual monitors. Traffic lights, highway barriers and variable message signs are in use to regulate 150,000 vehicles per day.
All bores are equipped with an automated height control at each entrance. As soon as a vehicle with a height of more than 4 meters enters the tunnel, the system will stop all traffic in that lane and direction of traffic. This will ensure that overheight trucks will not damage the tunnel. The tunnel fire brigade and tunnel police will then direct the truck out of the tunnel so that traffic can resume.
