The Tunnel Behringen lies between Arnstadt and Ilmenau in the Thuringian town of Behringen . It consists of two 465 m long tunnel tubes for the lanes of the federal highway 71 and a third tube for the new railway line Erfurt – Ebensfeld , which is unique in Germany.
The tunnel crosses under the Osterberg, a small wooded mountain ridge and foothills of the Reinsberge , with an overburden between 13 m and 31 m. Faults are crossed with layers of red sandstone and shell limestone ( Eichenberg – Gotha – Saalfeld fault zone ). The tunnel is crossed by the county road from Behringen to Arnstadt .
The construction of the tunnel is illuminated in the Niederwillingen Tunnel Museum .
Motorway tunnel
The motorway tunnel is at 92.5 km between the Arnstadt-Süd and Stadtilm junctions. The distance between the tubes is about 25 m. Each tube has a clearance height of 4.5 m and a clearance width of 9.5 m, which is divided into two 3.5 m wide lanes, edge strips of 0.25 m and emergency walkways on both sides of 1.0 m wide. The tunnel construction was carried out mechanically with excavators and shotcrete according to the new Austrian tunnel construction method. The tubes were driven from the northern portal. The standard cross-sectional area is 80.5 m², with the excavated material being installed in the subsequent sections of the route. The tubes are naturally ventilated. The tunnel was completed in 1998.
safety
In the middle of the tunnel, a cross gallery connects the two tunnel tubes and can be used by emergency vehicles. There are two emergency cabins for each tunnel in the direction of travel.
Railway tunnel
The double-track, 463 m long railway tunnel is located approximately 44 m west of the motorway tunnel between the route kilometers 163.287 and 164.750. The standard cross-sectional area of the maximum 13 m wide tunnel is 101 m². The tunnel has a cross-section measured for 4.70 m between the tracks, which is not used by the completed railway line. The other tunnels in the Thuringian section of the high-speed line have a cross-section reduced to 92 m² for a track spacing of 4.50 m, which goes back to a plan change from 1998. There is no emergency exit. The double-shell tunnel was built in the same period and with the same technology as the motorway. The tunnel was hit on March 7, 1997. On August 22, 1997 at 1:34 pm, the tunnel was symbolically broken through. The length of the structure is 463 m, the cover up to 16 m.
The structure has been unused for years since its completion. For the commissioning of the route, the tunnel was given a slab track , which can also be used by road vehicles. The commissioning for regular traffic took place as part of the line between Ebensfeld and Erfurt on December 10, 2017.
