Turmstraße Construction Site


The Turmstraße Bridge, as part of Bundesstraße 1a, has now been demolished, and a new bridge will be built. According to an expert opinion and an economic feasibility study (carried out by the City of Aachen), it was, unfortunately, no longer possible to renovate the bridge erected in 1971. The resulting change in traffic flow is set  to significantly affect RWTH Aachen University in many different ways – with consequences for motorists, public transportation users, cyclists, and pedestrians.

Since May 2, 2022, Turmstraße has been closed between Professor-Pirlet-Straße and Claßenstraße in both directions of travel. Four excavators were used to demolish the bridge one by one. At the same time, the railroad tracks under the bridge were uncovered, and the overhead lines were restored. According to the City of Aachen, the next steps include completing a protective scaffolding at the abutment and carrying out various works on the overhead line system. This special work can only be carried out when there is no train traffic between the Aachen West and Aachen Central stations. For this reason, further weekend closures will be set up in consultation with Deutsche Bahn. By December 31, 2022, these are planned as follows:

  • Saturday, December 17, 1am through Sunday, December 18, 9pm

The train service in the direction of Aachen ends in Herzogenrath. A rail replacement service (bus transfer) will be provided by Deutsche Bahn.

Due to upcoming work on the north abutment on the Schinkelstraße side, Geschwister-Scholl-Straße must be fully closed from Saturday, September 10, to Monday, October 10, even for pedestrian and bicycle traffic, according to the City. According to city officials, the abutment cannot be strengthened as planned but must be completely rebuilt. For this purpose, the remaining concrete parts of the abutment must first be demolished with large equipment, and an excavation pit must be dug to install the new foundation there. From mid-October, Geschwister-Scholl-Strasse will be reopened to pedestrian and bicycle traffic.

The entire construction project is scheduled for completion in December 2023. The City has planned for traffic to be routed around the construction site. For Alleenring, the immediate bypass goes via Claßenstraße, Seffenter Weg, Mies-van-der-Rohe-Straße, and Professor-Pirlet-Straße and is signposted in both directions. Templergraben is initially not part of the traffic rerouting concept and thus remains closed as part of the Living Lab project. The option of opening it at a later date remains.

This considerable interference with traffic flow has far-reaching consequences for RWTH Aachen University. Building access will be limited at times, and RWTH members should plan extra time to get to other buildings on campus or travel to RWTH – on foot, by bike, by car, or by public transportation. RWTH is not involved in this construction project but is in close contact with the City of Aachen to keep these restrictions as low as possible and communicate them quickly and transparently.

The City of Aachen has created a web page with the latest updates on the construction project. Please note that the information is only available in German.

The City of Aachen has also created the following email address for questions before and during the construction work: .
