Potholes - an expensive winter for the municipalities in the north - Northern Germany's roads crumble after brutal winter storms and freeze-thaw cycles

Harsh winter storms have left roads across northern Germany severely damaged. The repeated freeze-thaw cycles have created potholes and cracks, forcing local authorities into costly loans. Experts warn that quick fixes will not solve the long-term problem.

The damage stems from weeks of extreme temperature swings, which the ADAC calls a 'maximum stress test' for road surfaces. When water seeps into cracks, freezes, and expands, it breaks apart the asphalt. This winter's frequent fluctuations have made the situation worse.

Local crews are now patching the worst sections with cold asphalt. But a full assessment of the damage may not happen until late March. In Kiel, the problem is especially urgent—65% of the city's roads are over 35 years old and nearing collapse.

Municipalities are stretched thin, with no extra staff to handle the workload. Some will rely on their own public works teams, while others plan to hire private contractors. The German Asphalt Association estimates that frost-thaw damage has cost the country around €12 billion in loans over the past five years.

The ADAC stresses that emergency fixes are not enough. Without addressing the root causes, each winter will further weaken the roads.

Local governments now face a massive task to restore damaged infrastructure. The repairs will require time, funding, and better long-term planning. Without changes, the cycle of winter damage and temporary fixes is likely to continue.
