The 505-kilometer route from Perl via Karlsruhe, Stuttgart, Augsburg and Munich to the border with Austria is one of the most important east-west connections in Central Europe. Along the way, camera drones, bodycams and original sounds provide exciting stories to tell - from the highway police to truck drivers in the trucks to huge construction projects designed to relieve traffic. But the work on the approximately five-kilometer section near Pforzheim will continue for years to come. Instead of driving, traffic jams are the order of the day there until further notice. This ensures stress, long waiting times and increased risk of accidents.
