On behalf of the Federal Republic of Germany, represented by the Lower Saxony State Authority for Road Construction and Transport, Nienburg Division, the construction of a new bypass for the city of Wunstorf is to take place in the course of Bundesstraße 441.
The present draft provides for the construction of a bypass road in the north and east of Wunstorf. The construction route of the bypass runs within the municipal areas of Bokeloh, Wunstorf, Blumenau and Luthe of the town of Wunstorf.
The approx. 6.55 km long construction route of the bypass begins west of Wunstorf, swings out of the existing route of the main road in an arc and initially runs in an easterly direction north of the village of Wunstorf.
The route crosses between the village of Wunstorf and Klein Heidorn the municipal road Nordrehr and the regional road K 331 Klein Heidorner Straße. In the further course north of Wunstorf, the Bundesstraße 442 (Coppenbrügge-Bad Nenndorf-Wunstorf-Neustadt a. Rbge.) and the railway line 1740 Wunstorf-Bremerhaven are crossed with a trough structure.
The route of the OU bypasses the village of Blumenau in an arc to the north and east, crossing the regional road K 333 Leinechaussee and the water Westaue. After bypassing blumenau, the route of the OU initially runs in a southerly direction, crosses the regional road K 344 Manhorner Straße and connects between the villages of Wunstorf and Luthe in an arc to the existing federal highway 441 (Luthe bypass). The new line of the bypass ends immediately west of the overpass of the municipal road Im Blenze.
In addition to the traffic system, the construction project includes 1 trough structure, 7 bridge structures and 6 rainwater retention basins.
The estimated construction costs amount to around 62 million euros. The cost bearer is the Federal Republic of Germany.
A detailed description of the project can be found in the information document on the subject of the work.
