Due to the extension work on Tiefensteiner Straße, the B 422 is currently fully closed to through traffic in the area of the Historische Weiherschleife between the districts of Tiefenstein and Idar. The detour is generally via the L 177 through the local communities of Vollmersbach and Veitsrodt.
During the Veitsrodt premium market, however, the L 177 between Herborn and Veitsrodt will also be closed to through traffic. The detour route will therefore be relocated from Friday, July 11 to Tuesday, July 15, 2025. It will then lead from Idar and Oberstein via Saarstraße through Algenrodt to the B 41, from there to Rötsweiler-Nockenthal on the K 19 to Siesbach and via the L 175 to Hettenrodt. In the opposite direction, traffic will be diverted to the K 20 to Kirschweiler before it reaches the Kirschweilerbrücke bridge and then on to Hettenrodt. From there, it will take the described detour in the opposite direction.
- A map of the detour route is available on the city's website at www.idar-oberstein.de/baustellen.
