A81 highway obstruction during the holiday season, causing heavy traffic congestion in Baden-Württemberg.
This weekend (July 25–27, 2025), motorists in Baden-Württemberg should brace themselves for significant traffic jams and road closures due to planned A81 autobahn full closures for bridge construction work and increased traffic volumes during the summer holidays[1].
Key details:
- The A81 will be fully closed from Friday evening, July 25, until Sunday morning, July 27, 2025, between Sindelfingen-Ost and Böblingen-Hulb to install a temporary bridge at Wolfgang-Brumme-Allee[1].
- From July 19, the on-ramp at Sindelfingen-Ost toward Stuttgart is closed, so drivers coming from Sindelfingen to Stuttgart should use the alternative ramps at Böblingen-Ost or Böblingen am Flugfeld[1].
- These closures coincide with the summer holidays, which typically increase traffic volumes, especially on major routes like the A81[1].
- The full closure and ramp blocks will likely cause heavy congestion on detour and local roads near Sindelfingen and Böblingen.
Roads to Avoid:
- The section of A81 between Sindelfingen-Ost and Böblingen-Hulb during the closure period.
- The Sindelfingen-Ost ramp on the A81 toward Stuttgart is closed throughout the summer season starting July 19.
- Local roads near Wolfgang-Brumme-Allee might experience increased congestion due to detours and bridge work.
Recommended Alternative Routes:
- Use the A81 ramps at Böblingen-Ost or Böblingen am Flugfeld to enter the A81 toward Stuttgart.
- Consider avoiding the A81 if possible by using parallel routes such as the B14 or B27, depending on your exact destination.
- Stay updated on local traffic reports for smaller detours around Sindelfingen and Böblingen.
Additional notes:
- A temporary foot and bike bridge ("Elefantenbrückle") is in place over the A81 since late 2024; bus traffic will also be rerouted via this new temporary bridge[1].
- A further 55-hour full closure of the same A81 section is planned August 8–11, 2025, for the demolition of an existing bridge, so travelers should plan accordingly if their trips extend into early August[1].
Besides the A81, traffic restrictions are likely to occur on the A5, A6, A7, A8, and B31 routes. Traffic jams are expected on the A5 between Heidelberg and Baden-Baden, although the exact locations are not provided.
On the A81, traffic jams are expected between Mundelsheim and the Leonberg junction, between the Stuttgart and Herrenberg junctions, and in the area of the Hegau junction. However, the specific section of the A81 that will be closed has not been specified.
Given these circumstances, motorists are advised to inform themselves about the traffic situation on the roads and plan alternative routes if necessary. Those familiar with the area are advised to avoid the affected areas entirely. High travel and leisure traffic is expected in Baden-Württemberg due to the A81 closure and the summer holidays.
The planned full closure of the A81 autobahn for bridge construction work from July 25 to 27, 2025, will significantly impact the lifestyle of motorists in Baden-Württemberg, as traffic jams and road closures are expected, especially near Sindelfingen and Böblingen. To avoid heavy congestion, consider using alternative routes such as the A81 ramps at Böblingen-Ost or Böblingen am Flugfeld, or taking parallel routes like the B14 or B27 based on your destination.
