A 400 m long tunnel in the Lower Saxony municipality of Bovenden is known as the Bovender cover . The lid emerged from lengthy discussions and mainly serves to protect residents from noise. It takes up two tracks each on the high-speed line Hanover – Würzburg , the line between Hanover and Kassel and the federal highway 3 .

construction

The structure consists of three troughs of 11.25 m (north-south route), 13.85 m (new route) and 13.00 m (main road) width. The main road is arranged on the west side, the new line runs in the middle and the existing line on the east side of the structure.

The building is covered with earth and greened.

history

initial situation

During the construction of the Hanover Southern Railway, the route ran along the east side of what was then the village of Bovenden. Due to the expansion of the place, settlements arose east of the route, which were connected to the old settlement systems by two bridges. Before construction began on the new line, the north-south line crossed the patch in a cut up to nine meters deep.

planning

In the planning phase of the high-speed line, the simultaneous crossing of the new line and the federal highway 3 to be routed in this section caused particular problems due to the cutting of the previous railway line . The original plan was to route the new line through the existing section of the southern runway, with supporting walls being built on both sides . The resulting trough , including the federal road that was also included in the planning, would have been 40 m wide. Several houses would have been affected by these measures.

The 800 m long passage through the town center should initially take place in a cut up to 8 m deep. The new line should be led 1.30 m below the level of the north-south line in order to achieve the required clearance under bridges. Landscape architects commissioned by the DB had developed the planting of the cut edges with fruit trees in order to take up the “character of Bovenden with its orchards and groups of trees”. The regional planning procedure was completed on September 30, 1977; then preliminary drafts for the plan approval were drawn up. At the end of 1979, Deutsche Bahn expected to be able to initiate the plan approval procedure for the Bovenden area (plan approval section 3.6) "shortly".

The municipality of Bovenden, on the other hand, requested a 400 m long cover over the three traffic routes, while the Federal Ministry of Transport initially only wanted to promise a cover about 125 meters long. The detailed planning began immediately after the completion of the regional planning procedure, in 1980. In autumn 1981, a cut up to ten meters deep was planned. The existing incision should be widened by retaining walls in order to avoid interfering with the surrounding buildings. The north-south route was to be moved to the eastern edge of the cut and a freight train track overtaking track should be left open.

The procedure was further complicated by the planned re-routing of the B 3. After initially planning a western bypass of Bovenden through the trunk road and received approval from those involved in the spatial planning process, the road planners later spoke out in favor of parallel routing of the new route and the federal road for economic reasons . In the course of the spatial planning procedure for the B3, this parallel route was gradually demanded by everyone involved, as was the suspension of the planning approval procedure for the new route until the route for the B3 had been clarified. The regional planning procedure for the B3 was completed in August 1981, with the requirement that the federal road should be laid to the west parallel to the new line through Bovenden. This made a joint planning approval procedure necessary for the new line and the federal highway. The Federal Minister of Transport was responsible for the decision to partially cover the trough.

In mid-1983 no underground route was planned in Bovenden. At the end of 1985, the Federal Minister of Transport finally granted approval for the 400-meter coverage.

The Bovenden section, as the last of the nine plan approval sections between Northeim and Göttingen, was approved in July 1986. In July 1987, when all other planning approval decisions had already become final, the decision for the Bovender section was still pending. In May 1988 a lawsuit was still pending in the Bovender section, whereby the construction work had already started due to an ordered immediate execution .

In the planning phase of the high-speed line, the cover belonged to the 27 km (75.5 to 102.5 km) long planning section 3 (Edesheim – Göttingen) of the line in Lower Saxony. It was assigned to construction lot 314, between the Nörten-Hardenberg train station (km 91.300) to the Bovenden district boundary (km 95.180).

The tracks on the north-south line were re-routed in the Bovenden area over a length of 2.0 km.

Construction work on the lid began in July 1986.

The structure was completed in 1989. On September 29, 1989, a so-called "lid festival" was celebrated.

Effects

According to the railway, the noise pollution in Bovenden was reduced by up to 20 dB (A) due to the building. The subjectively perceived noise pollution in the town center should decrease to up to a quarter of the original value.
