The extension work on Tiefensteiner Straße between Weiherschleife and the Grimm retirement home will begin one day earlier, on Tuesday, March 4, 2025. The road and sidewalks will be extended over a length of around 440 meters and the street lighting and supply systems for water, sewer, gas, electricity and telecommunications will be renewed or renovated.
To carry out the work, the B 422, Tiefensteiner Straße must be completely closed to through traffic and a large-scale detour route will be designated. During the work, the Weiherschleife parking lot will remain accessible from the direction of Idar, and in the first construction phase it will be possible to drive from the direction of Kirschweiler as far as the Barth & Frey car dealership.
Detour via Veitsrodt and Vollmersbach
All through traffic (cars, lorries and public transport) from Idar and Oberstein, which normally travels via the B 422 through the Tiefenstein district, will be diverted from the main road to Vollmersbachstraße at the traffic circle at the OIE building and routed along the L 177 through Vollmersbach and Veitsrodt. From the traffic circle between Veitsrodt and Herborn, the route continues on the L 175 and Herrsteiner Straße to the traffic lights at Wagners Eck in Tiefenstein. The detour route ends there. Traffic coming from Hettenrodt and Kirschweiler in the direction of Idar and Oberstein will use the same route in the opposite direction.
You can find a map of the detour route on the website www.idar-oberstein.de/baustellen.
Detour during the Veitsrodt premium market
During the Veitsrodt premium market from July 11 to 14, 2025, the L 177 between Veitsrodt and Herborn will be closed. The detour route will therefore be relocated during this time. 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. Before reaching Hettenrodt, traffic will take the detour described above in the opposite direction.
Bus transport
Several bus lines are also affected by the detour, namely the 800 (Hochwald-Schnellbus) Idar-Oberstein to Trier, 804 Idar-Oberstein Bahnhof to Tiefenstein, 840 Idar-Oberstein to Wittlich, 845 Idar-Oberstein to Morbach as well as school trips on lines 845, 847 and 850S. Information on the changed routes and departure times can be found on the Internet for line 804 at Nahverkehrsbetriebe Birkenfeld at www.nvbir.de, for the other lines at Scherer Verkehrs GmbH at www.scherer-svg.de or overall at Rhein Nahe Verkehrsverbund at www.rnn.info.
As some of the bus routes will pass through Bachweg in the Tiefenstein district during the detour, a stopping ban will be introduced at the junctions with Herrsteiner Straße and Tiefensteiner Straße in both directions.
At the Idar market square, the current parking signs at the bus bay in front of the former market school building will be removed. For the duration of the detour, the area will be used as a waiting area for buses on routes 840 and 845.
The city administration asks road users and residents for their understanding for the inconvenience caused by the construction work.
