Temporary Access Road to Häldenmühle: Construction Begins on June 24

To ensure that the wastewater treatment plant, the composting facility, and the community gardens in the Häldenmühle area near Murr and Marbach am Neckar remain accessible during the ongoing major construction projects at the Murr Bridge and the Oehler intersection, the district administration, on behalf of the state, is establishing a temporary access road from the L 1100 to the farm road “In der Au.” Construction work will begin on Wednesday, June 24, 2026, and is scheduled to be completed by July 29, 2026, the start of summer vacation. The work will take place alongside the L 1100 between the Bergkelter intersection and the “Steinbruch” tunnel.

The first construction phase will involve building the actual access road

The project will be carried out in two construction phases. In the first phase, the main access road will be built within about three weeks. Subsequently, in the second phase, a traffic light system will be installed on the L 1100 just before the “Steinbruch” tunnel entrance. An additional one to two weeks are scheduled for this work.

The speed limit in the construction zone is 30

During the construction period, drivers on the L 1100 should expect traffic restrictions. Due to narrowed lanes, a 30 speed limit applies in the construction zone. However, a detour is not necessary. On the dirt road “In der Au” between the wastewater treatment plant and the bike path junction leading to the Murr Bridge underpass, increased construction traffic is also expected. There will be no changes to bus service for the time being.

After summer break, access to Häldenmühle from Marbach will be possible again

The temporary access road is intended solely to ensure access to the affected facilities and properties during the construction phase of the Oehler intersection. After the summer break, access to the Häldenmühle from Marbach will be possible again. At that time, access to the wastewater treatment plant, the composting facility, and the community gardens will once again be via Marbach. The temporary access route will then be used by bus lines heading toward Marbach.

The state will cover the construction costs of approximately 470,000 euros. The District Office asks all road users and residents for their understanding regarding the disruptions and restrictions.
