Tunnel Saukopf near Weinheim remains closed for extended period

The Saukopftunnel, which connects the regions of Hesse and Baden-Württemberg, has encountered an unexpected setback in its planned reopening. Originally scheduled for the end of October 2025, the tunnel's reopening has been delayed due to an unforeseen defect in the control of the smoke extraction louvers.

The issue was announced by the Karlsruhe government district, and it has been revealed that more than half of the 36 smoke extraction louvers in the tunnel are not controllable after the completion of the recent renovation work. This malfunction poses a "serious safety risk" as smoke and harmful combustion gases cannot be sufficiently vented from the tunnel in case of fire.

The Saukopftunnel was closed at the end of July for renovation work on safety technology, with the work taking place between Weinheim (Rhein-Neckar district) and Birkenau (Bergstraße district). However, the closure has been extended due to this unforeseen defect, and the reopening date is currently uncertain.

Authorities are working diligently to fix the failure in the control of the smoke extraction louvers. The Karlsruhe government district did not provide a specific reason for the defect in their announcement. If you need the latest updates or any changes to this timeline, checking official announcements from the responsible transport authorities would be advisable.

The Saukopftunnel's delayed reopening is a significant inconvenience for commuters and travellers alike, as it is a crucial transportation link between the two regions. The problem with the smoke extraction louvers is not functioning properly, and this has raised concerns about the tunnel's safety.

In the meantime, it is essential to prioritise safety and follow any travel advisories issued by the responsible authorities. Stay tuned for updates on the Saukopftunnel's reopening and any progress made in resolving the issue with the smoke extraction louvers.
