Map with all coordinates: 
The Wagenburg tunnel is an 824 meter long single-tube two-way traffic tunnel in Stuttgart . It is part of Landesstraße 1014 and connects Wagenburgstraße in the east of Stuttgart with the Gebhard-Müller-Platz intersection in downtown Stuttgart , which is near Stuttgart's main train station . The tunnel crosses under the Uhlandshöhe , shortening the route between the city center and Ostheim or Gablenberg .
history
The plans go back to the 1920s. For financial reasons, however, the project was initially postponed.
On November 21, 1940, discussions with the advisory councils on air protection issues began in the Stuttgart municipal council as a result of the Fuehrer's decree of October 10, 1940, according to which bomb-proof air raid shelters had to be built on a large scale in Stuttgart.
At that time, buildings that could be used for other purposes in peacetime were also considered air raid shelters, such as B. Tunnels and underpasses. With the search for a suitable large air raid shelter, the ridge between the main train station and the east of Stuttgart became the focus of interest again.
The air protection officer appointed by Mayor Strölin , Senior Building Officer Scheuerle, presented the plan for a 780 m long tunnel with two tubes, each ten meters wide, which was generally approved. On November 22nd, 1940 the advisory councils for air protection issues visited the Engelberg tunnel in Leonberg to get further suggestions.
In the spring of 1941, the construction of visible tunnels, which were continuous, began. The complete cross-section has not yet been reached.
The breakthrough was celebrated in 1941. The partially completed tubes were used as a large air raid shelter for up to 15,000 people during the Second World War . In addition, art objects were also stored. For example, the Schiller monument was dismantled by Thorwaldsen at Schillerplatz and taken to the Wagenburg tunnel on June 19, 1942. Only after the end of the war was it put up again on Schillerplatz.
In 1946, the local council decided to expand the south tunnel for vehicle traffic. When it opened on March 17, 1958, the Wagenburg tunnel was the longest road tunnel in Germany. It is defined as a motor road , so pedestrians and cyclists are prohibited from entering. From the beginning, a Stuttgart tram line also ran through the tunnel, today's line 40 (until 1978 referred to as line Ga after its destination in Gablenberg ).
The north tube was only expanded to 170 meters and, as the car-friendly city was abandoned after a while and the east of Stuttgart was not burdened with additional traffic, it was never completely completed. According to the city of Stuttgart, structural aspects played no role in this decision. According to other sources, the problematic geological situation with extensive anhydrite deposits caused the construction work and the costs to be expected to rise sharply. During the construction of the south tube, the workers encountered swellable gypsum keuper, which began to rise. It was then decided not to finish building the north tube. It was later developed as an escape route and served the music club "Die Röhre" from 1985 to 2012. Since then, the reinforced concrete shell has been destroyed several times and the area above it has been lifted.
Part of the Nordröhrentunnels (west portal) was used as a venue for independent concerts and by the “Die Röhre” disco. The eastern part of the connecting tube was expanded from 2001 to 2003 as an escape route from the road tunnel.
The tunnel portals have been particularly emphasized since 2008 (on the occasion of the 50th anniversary). The lower one is painted green and the upper one blue, both are illuminated at night.
From 2009 to 2010 the western part of the connecting tube was renovated and a third escape access dug from the main into the connecting tube.
Stuttgart 21
The Filder Tunnel and Obertürkheim Tunnel planned as part of the Stuttgart 21 project will each cross under the Wagenburg Tunnel with two tubes. The northern tube of the Untertürkheim tunnel will be around 38 m lower than the Wagenburg tunnel.
A rescue area for the Filder tunnel is to be built in front of the west portal. From there, a 222 m long rescue tunnel is to be built to the Filder Tunnel and the approach area Central Station South , which can be used by rescue vehicles and largely follows the course of the north tunnel . The discotheque “Die Röhre” was therefore closed on January 15, 2012. On January 22nd, 2012, as a first measure of the construction site equipment, about 30 trees were felled in front of the north tube. The construction of the construction site began in April 2013.
The part of the north tube that is not required for the rescue access is to be backfilled and sealed.
As part of the construction work, the Wagenburg tunnel is to be temporarily closed to preserve evidence from the buildings above.
