Full closure on Weinbrennerstrasse: diversions from June 23rd!
In Lörrach, the next few weeks will be dominated by the expansion of the district heating network. Work on Weinbrennerstrasse will begin on June 23, 2025 and is expected to last until July 27, 2025. During this time, access from the Aichele node direction will be completely closed, but there is good news for all users: access to the Burghof car park remains possible. This is particularly important because the parking garage remains accessible even during construction work.
The city administration has already taken measures to redirect traffic. Road users coming from the state border will be informed of the closure at the Basler Straße / Schillerstraße / Clara-Immerwahr-Straße roundabout. There is a detour for them via Clara-Immerwahr-Strasse, Wiesentalstrasse and Teichstrasse. A diversion via Basler Straße and Clara-Immerwahr-Straße to the B 317 is also planned for traffic from the direction of Baumgartnerstraße and the railway crossing.
Important information for cyclists and buses
Despite the construction work, the passage will remain open for cyclists and scheduled services traveling south. Cyclists can bypass the construction site from the Aichele junction via the pedestrian zone on Basler Straße and Herrenstraße. This means there is a clear and safe route for environmentally friendly means of transport, while motor vehicle traffic is affected by the closed passage. You can reach the district hospital from the south at any time via Teichstrasse, Gugelmeierstrasse, Weinbrennerstrasse and Spitalstrasse.
“The city administration asks all road users to understand the restrictions during the construction period,” explains a city spokesman. It is ensured that traffic routes are clearly signposted and diversions are well communicated. The information about the diversion will be found at the relevant points, such as Spitalstrasse and Wiesentalstrasse/Teichstrasse.
Outlook for the next construction phases
In the first construction phase, which lasts until July 18, the northbound lane will be completely closed, while southbound passage remains possible for cyclists and buses. From July 21st, the second construction phase will follow between the Aichele node and the retirement community, where similar regulations will apply again. The city will create special diversions for the construction site area between the retirement home and Weinbrennerstrasse 5, which will be communicated in good time.

How difu.de reports, public technical infrastructures are currently changing, and the city wants to develop future-oriented solutions to meet the need for energy and heat supply.

It remains exciting to see how the city will develop in the coming period - after all, there is a lot to be said for a future-proof and sustainable infrastructure for everyone in Lörrach.
