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.

Famous quotes containing the words height and/or control:
“The height of cleverness is being able to conceal it.”
—François, Duc De La Rochefoucauld (1613–1680)
“There are many things children accept as “grown-up things” over when they have no control and for which they have no responsibility—for instance, weddings, having babies, buying houses, and driving cars. Parents who are separating really need to help their children put divorce on that grown-up list, so that children do not see themselves as the cause of their parents’ decision to live apart.”
—Fred Rogers (20th century)
