Traffic collapse ahead: B500 closure in Baden-Baden from Monday!

From Monday, September 29, 2025, the B500 in Baden-Baden will be partially closed. The reason is the preparations for the demolition of the outdated Oostal Bridge, which is proving to be a problematic construction site for traffic. This main artery, which connects the city with the Black Forest High Road, is already often overloaded - especially on weekends and at peak times. According to a report by bnn.de The traffic jam sometimes extends as far as Oos and Lichtental and is further exacerbated by numerous events.

The demolition of the Oostal Bridge will not only pose a challenge for traffic planning, but will also last for several years. Residents are affected by increased disruption and potentially longer waiting times. The city and the regional council have announced that they will closely monitor the situation in order to be able to plan improvement measures in good time.

Geotechnical investigations and further preparations

In order to ensure safety during the construction site, geotechnical investigations will begin on September 29th and are expected to last until November 7th, 2025, according to the Karlsruhe regional council. These investigations take place on one side of the B500, which can lead to temporary restrictions and speed limits. The affected residents have already been informed about the upcoming measures, and the regional council asks for your understanding of the inevitable burdens. Detailed information about this can be found on the regional council’s project page.

The exploratory drilling carried out by KREBS+KIEFER Ingenieure GmbH is part of the extensive plan for the renovation of 31 bridges in need of renovation, which has been initiated by the state of Baden-Württemberg since October 2024. The Oostal Bridge is also highlighted as a specific project that contributes to the renewal of the infrastructure.

Infrastructure challenges

The modernization and the associated measures are part of a larger trend in Germany, where around 40,300 bridges are responsible for the transport infrastructure. Many of these bridges, built between 1960 and 1985, no longer meet today's requirements for load-bearing capacity and traffic safety. The Ministry of Transport has launched a bridge modernization program that aims to bring the transport infrastructure into shape and increase safety for all road users bmv.de described in detail.

Overall, the situation in Baden-Baden is a prime example of the challenges associated with the maintenance and renewal of transport routes. The impending demolition of the Oostal Bridge and the associated investigations are the first step in a longer process that will require both patience and flexibility from drivers and residents.

The city administration is actively working to make the transport infrastructure future-proof and to make necessary adjustments, while citizens are asked to keep track of the current conditions via the VerkehrsInfo BW app.
