B3 Südschnellweg
Hannover

The historic B3 transport corridor through the state capital, Hanover, has been undergoing refurbishment since 2023. The PORR/PORR special civil engineering/Hagedorn consortium was awarded the contract by the Niedersächsischen Landesbehörde für Straßenbau und Verkehr to carry out the first major section of the modernisation of the Südschnellweg.

A selection of images.
Drone shot of the Südschnellweg; you can see the traffic situation from above; there is a lake in the background;
It is dark, a gigantic steel structure hangs from a crane and hovers above the ground. Work is going on around the steel part.
Two construction workers install prefabricated parts on steel girders on the Südschnellweg in August 2024.
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.
