Wyhlen bypass bridge opens May 4 to cut traffic congestion
A major phase of construction on the Wyhlen bypass is nearing completion. On Monday, May 4, 2026, the new bridge on Am Wasserkraftwerk road, spanning the future B34 bypass in Grenzach-Wyhlen, will open to traffic. According to the Freiburg Regional Council, vehicles will be rerouted from the temporary detour onto the new structure.
Drivers should expect temporary disruptions, including lane restrictions in certain sections. Pedestrians and cyclists will also face changes—they will once again be diverted via Degussaweg for the remainder of the construction work.
Work on the pedestrian and cycle paths, as well as the guardrails, is expected to be completed by the end of May. After that, the temporary bypass will be dismantled.
The new bridge marks another step toward relieving traffic congestion in Wyhlen.
