The picture shows the opening of the Südschnellweg to traffic.
The image shows a construction site where a large Caterpillar (CAT) excavator is demolishing a concrete structure. The arm of the excavator is extended and the bucket is breaking apart the concrete, creating debris. There are metal beams and rubble scattered around the area.
