Danger of collapse in Oldenburg: underground car park must be renovated as quickly as possible!
In Oldenburg, the topic of the risk of collapse of a low-lying garage has come up. This is located under a busy main road and the city has now announced serious measures to prevent anything worse from happening. How NDR reported, an acute risk was identified through the assessment of the building structure by a structural engineer. The city administration is alarmed and city councilor Holger Denckmann has responded to the emergency situation with a rapid implementation plan.
The city of Oldenburg will install an auxiliary steel structure in January 2026 to ensure the stability of the underground car park. These measures are necessary because the ceilings and walls have significant defects. Until the renovation is complete, a close monitoring system will be set up to monitor the underground car park to ensure the safety of the adjacent museums and residential and commercial buildings.
Long-term renovation planned
The long road to comprehensive security will not be easy. Since 2019, parking spaces in the two-story underground car park have been closed due to safety concerns. Currently, only 75 of the 500 parking spaces are still usable; the rest are blocked due to stability issues. The approximately 425 closed parking spaces have already received temporary support.
The city apparently underestimated the danger for a long time and security measures were delayed. The structural engineer had already pointed out the urgency of the renovation in May 2025. The fundamental renovation will require extensive construction work that could last at least until 2029, with an estimated total cost of 44.5 million euros.
Costs and financing
The city council has already budgeted a total of 1.85 million euros for 2025 and a further 4.5 million euros for 2026. Part of the financial resources could be covered by urban development funding amounting to around 2.7 million euros. According to experts, it will not be possible to fill the underground car park with concrete or sand to stabilize it, as this would put additional strain on the subsoil.
The challenges facing the city are not only a question of capacity and costs, but also of security for citizens and the preservation of the neighboring cultural sites. The buildings in question date from the years between 1958 and 1972 and may have been built with defective supports. The district has given the all-clear for now, but drivers should be careful and not all vehicles drive on the bridge above.
It remains to be seen how the situation will develop, but one thing is certain: the city of Oldenburg has a “good hand” for quick solutions, and the safety of its citizens has top priority.
