From April 15 to 26: 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 15 to 26.

A specialized machine equipped with a high-pressure cleaning attachment is actively cleaning the underside of a bridge. Water sprays forcefully from the nozzle, creating mist, under dim lighting conditions. The scene is set within a tunnel environment, showcasing maintenance work in progress.
