Full closure of the L 1100: Major construction site in Ilsfeld will start soon!
A lot is happening in Ilsfeld: On Sunday, July 13, 2025, work will begin on the third construction phase on the L 1100. This measure is part of an extensive renovation project that includes both the renovation of the roadways and the conversion of several junctions. To ensure that the construction site progresses quickly, the L 1100 and the two motorway entrances will be completely closed during the construction period. According to the plan, the work will last until September 7, 2025, which means that the traffic situation in the region could change slightly during peak hours. [rp.baden-wuerttemberg.de]. Auenstein.
Diversions are extensive to keep traffic flowing. Drivers in the direction of Untergruppenbach and Wüstenhausen are asked to continue on the L 1100 towards Flein to the forest intersection. From there you take the K 2155 to Untergruppenbach and the K 2086 back to Wüstenhausen. The same diversion applies in the opposite direction for the direction of Lauffen / Flein. If you want to go to Beilstein or Ilsfeld, use the K 2156 to Pfahlhof and return to Auenstein via Winzerhausen and the K 1617. In addition, the P+M parking lot in Ilsfeld will remain completely closed until December 15, 2025, which will certainly pose challenges for some commuters.
Cyclists and pedestrians redirected
Cyclists also have to be prepared for diversions, as the cycle path from the Aral gas station to the entrance to Ilsfeld is closed. You can use the main street in Auenstein, the Eisenbahnstraße and the cycle path along the Schozach to get to Ilsfeld. These restrictions demonstrate that great attention is being paid to the safety of all road users during construction.
With an investment volume of around 5 million euros, the entire measure is not cheap, but the improvement of the infrastructure will have a long-term positive impact on traffic conditions in the region. A further look at current investments shows that North Rhine-Westphalia in particular is investing generously in its transport infrastructure in 2025. Around 600 million euros will flow into the maintenance and expansion of roads and cycle paths there, as umweltwirtschaft.nrw.de reports.
The coming weeks will be exciting, and we ask citizens to understand the disruption that the construction work will cause. We will inform you in good time about further developments and details about the future construction phases.
