Cleaning of the A7 also at night
According to Autobahn GmbH, the roadway will be cleaned in sections. Stephan Fürsten, head of the responsible motorway maintenance department, said they would also work through the night.

Fürsten announced that the top speed would also be limited to 80 kilometers per hour along the entire route in the coming days.
Sweepers manage 500 meters per hour
