The major infrastructure project, which began with the replacement of the old railway bridge in September last year, is set to continue until the end of 2026. Until then, the route will remain closed to car traffic, and pedestrians and cyclists will also have to wait significantly longer before regaining access.
For two consecutive nights, residents living near the site were kept awake by the noise of concrete mixers as work continued on the underwater concrete base for the new underpass. This base must fully cure before construction can proceed. According to Deutsche Bahn, the passageway between Breslauer Straße and Gröbenzeller Straße will remain closed to all traffic for the time being. While car drivers can bypass the site using designated detours via Baubergerstraße or Pelkovenstraße, pedestrian and bicycle access will remain limited. Temporary routes do exist, but their usability is inconsistent, and no further details have been provided by the rail operator.
The company confirmed that pedestrian and cyclist access will not be restored until the end of 2025. Until then, the underpass area will remain inaccessible to non-motorized traffic. Despite the long timeline, Deutsche Bahn reported that the project is progressing according to the original schedule.
Expanded Underpass to Improve Safety and Accessibility
The goal of the renovation is to lower the underpass, allowing for increased clearance for vehicles and improving traffic safety. The new structure will also include a wider passage to accommodate separated paths for pedestrians and cyclists, as well as a turning lane for vehicles running beneath the bridge. City officials and Deutsche Bahn have emphasized that the redesign is aimed at significantly enhancing traffic safety in the area.
The next major step will involve the pumping out of groundwater that entered the excavation pit earlier this year, causing initial delays. Only after the drying process is complete can construction begin on the so-called “groundwater trough,” which is expected to be completed by 2026.
Project Budget Remains Stable at €13 Million
The total cost of the project is estimated at approximately €13 million. As of now, Deutsche Bahn reported no indications of cost overruns. “We remain within the planned investment framework,” said a company spokesperson. In addition, there was welcome news for residents: no further nighttime construction work is planned, meaning nearby homes can look forward to quieter nights for the foreseeable future.
