Map with all coordinates: The junction structure Oberzwehren is a railway - flying junction in Kassel . It is located in the Kassel district of Oberzwehren and therefore bears his name. On the structure, the Main-Weser-Bahn coming from Kassel-Wilhelmshöhe station crosses the high-speed line Hanover-Würzburg in a 1152 m long tunnel in a south-easterly direction.
In the northern part of the crossing structure is the Oberzwehren stop of the Main-Weser-Bahn, which is served by regional trains , RegioTrams and trains from Cantus Verkehrsgesellschaft .
course
To the north of the structure, the two tracks of the new line run centrally between the two outer tracks of the Main-Weser Railway. A number of switches connect the four tracks.
On the structure, the gradient of the new line drops in a southerly direction, while that of the Main-Weser Railway initially rises. Then the two tracks of the Main-Weser Railway will be brought together. This is followed by the Oberzwehren stop. In the further course, its route swings to the east from the new line running south.
At the southern edge of the structure, the new line, still in the tunnel, passes under the federal highway 49 . The Main-Weser-Bahn passes under the trunk road immediately east of it in an open route.
Both portals of the 1152 m long tunnel have trough structures in front of them.
At 51 ° 16 '14.2 " N , 9 ° 27' 15.5" O and 51 ° 16 '34 " N , 9 ° 27' 11.9" O are the two exits of the tunnel.
history
background
Before the construction of the structure, the Main-Weser Railway ran on an approximately 20 m high dam, which was bordered on both sides by 20 m high poplars . As part of the construction work, the poplars were felled, the dam was lowered by around 3 m and noise barriers were built. In the Oberzwehren district, 2 to 10 m high soundproofing dams were built in a 5 to 10 m deep cut to the west of the Keilsberg .
planning
According to the planning status of 1983, a 60 m wide and up to 17 m high dam was planned in the area of the residential area of Oberzwehren.
After objectors feared a worsening of the local climatic conditions in Kassel as part of the plan approval procedure (due to impairment of the movement of cold air by the planned dam structure) in Kassel, the German Weather Service was commissioned with an expert opinion, which was presented in 1984. It recommended a planting of the embankments and changes in two sections.
In 1984 the tunnel was planned with a length of 1147 m and costs of 69.7 million DM.
construction
The first groundbreaking took place in October 1988. It marked the start of construction for the last major construction project in the course of the new line. During the construction period, around 240,000 m³ of soil were excavated and 72,000 m³ of concrete were used. Two pedestrian bridges were also built in the course of the construction project.
The construction time in 1988 was calculated at 34 months. The planned investment (as of 1988) was 55 million D-Marks. The crossing structure was fully commissioned in 1991.
