From April 8 to 30: Major cleaning of the road tunnels in the district

Once a year, the road tunnels in the Ludwigsburg district undergo a major clean. This year, the cleaning and maintenance campaigns will take place from April 8 to 30.

The work in all tunnels includes cleaning the tunnel ceiling and walls with a special machine, cleaning the drainage systems and maintaining the lighting systems and technical equipment.

For traffic safety reasons, the tunnels will have to be temporarily closed to public traffic during the work:
