Project planning engineering structures and specialist planning structural engineering

The overall measure includes the construction of the Idstein-Eschenhahn bypass as part of the B 275 federal road and a new connection of Idstein-Eschenhahn to the bypass, including the construction of a bicycle and pavement bridge along the Eisenstraße, the construction of a Limes and business route overpass and the construction of a viaduct across the Auroffer stream.

The structure is to be built from construction km 2+390 to construction km 2+774. Since Idstein-Eschenhahn only has the connection to the west of the village, at the end of the construction work from the town exit of Eschenhahn in the east until the new route is looped onto the existing federal highway, the road will be graded to an agricultural and forestry path and rebuilt to a 4 m wide gravel road. The newly created path also serves as an operating path to reach the bridge abutment of the Auroffer Bach viaduct (BW 4) and the retaining wall (BW 5) at construction km 2+784.

The old B 275 and K 708 will be dismantled into an economic route as a crossing option for bicycle and pedestrian traffic in an easterly direction. This opens up the possibility for bicycle and pedestrian traffic to reach the city of Idstein and its parts of Ehrenbach and Oberauff by crossing under the Auroffer Bach Viaduct (BW 4).
