Renovation of the B100: goodbye to potholes! Construction work will start soon

The upcoming renovations on the B100, which will begin on September 8, 2025, are intended to significantly increase traffic safety on over 20 kilometers of the route. This extensive work includes repairing potholes, cracks and other damaged areas of the road and is being carried out with a total investment of 150,000 euros as part of the autumn offensive.

The renovation is being carried out as a mobile construction site, which means that the work will be carried out in sections. During construction work, the B100 will only be accessible in one lane in the affected areas, and you will be required to wait if there is oncoming traffic. The renovation measures include both new asphalting and the thorough renovation of damaged areas in order to ensure long-term improvement in the condition of the roads.

Background to road damage

Damage to roads, such as the one being repaired on the B100, is not an isolated case. In Germany, for example, the road network suffers from chronic congestion. Federal government forecasts from 2014 show that traffic congestion, particularly in truck traffic, could increase by 39 percent by 2030. This high load leads to increased pavement damage, including cracks and potholes, caused by overloading as well as weather and road construction errors.

The elasticity of the asphalt is crucial in order to recover after pressure loads. High temperatures in summer reduce this elasticity, leading to irreversible compression deformation. Material fatigue, frost, UV radiation and temperature fluctuations can also damage the elasticity of the bitumen and cause microcracks. These cracks increase the risk of erosion and frost cracking, which can lead to a vicious cycle of further damage.

Reasons for thorough renovations

A thorough road renovation, as is also being considered for the B100, includes the complete renewal of the entire road structure and surface. This measure not only makes it possible to repair serious damage, but also makes significant changes to the road space layout. This affects roadways, sidewalks and green spaces and offers the opportunity to better adapt public spaces to climate change.

The focus here is on improving traffic safety and the quality of life for residents. Restoring the road to good condition not only increases the lifespan of the infrastructure but also improves the quality of travel. Creating green spaces can also improve environmental quality.

The initiation of renovation work on the B100 is therefore a necessary step to ensure traffic safety and to address the ever-growing infrastructural challenges.
