Map with all coordinates: 
The Heckenstallerstraße tunnel is a road tunnel in the south of Munich . Along with the Luise Kiesselbach tunnel, it is the second tunnel in the Mittlerer Ring Südwest project . Its length is 620 meters. It was officially opened on July 25, 2015 and opened to traffic on July 27, 2015. It is named after Urban Heckenstaller .
location
The Heckenstallerstraße tunnel is located in the Sendling-Westpark district and around four kilometers southwest of Munich city center. It runs in a west-east direction and under the previous Heckenstallerstraße. In the west the tunnel is bounded by Friedrich-Hebbel-Straße, in the east by Passauerstraße.
history
First planning and setback
Since the 1970s at the latest, there have been plans to move the Middle Ring underground in southwest Munich. When the Westpark underground station was built (opened in 1983), the construction of a road tunnel was already included in the planning. At the end of the 1980s, the engineering structure was completely planned. At the coalition negotiations on red-green in the Munich city council in 1990, however, at the insistence of the smaller coalition partner , the SPD and the Greens agreed not to pursue any further tunnel projects for the Middle Ring.
Referendum
1995 brought some CSU -Politiker through a citizens' petition, entitled "Three tunnels need the Middle Ring" the first Munich referendum on the road. On June 23, 1996, the Munich voters decided with a narrow majority in favor of a further expansion of the Middle Ring and against the will of the city council majority made up of the SPD and the Greens.
planning
The plan approval procedure ran from 1999 to 2003. The plan approval decision followed in February 2003. The government of Upper Bavaria approved the tunnel on the condition that low-vibration technology was used during construction and that construction times and the implementation of evidence-preserving procedures were observed. In the areas in which the tunnel is immersed in the groundwater layers, water management issues must be taken into account.
The tunnel construction was originally supposed to start in 2005. Due to the financial difficulties of the city, the project approval by the Munich city council did not take place until April 2007.
Construction progress
General
The tunnel was built using the top-down method. First the tunnel walls (bored pile walls) and the tunnel ceiling were constructed. In the second step, the excavation took place under the tunnel ceiling with the construction of the roadway floor. The final step was the final technical development.
In mid-2009, the building department set up an information container on Luise-Kiesselbach-Platz to inform the public .
Tunnel services
The entire "Middle Ring Southwest" project was divided into five construction lots. The Heckenstallerstraße tunnel represents section E. After the start of the laying of the supply lines (gas, water, sewage), planning for construction and provisional traffic management began at the end of 2007. The Europe-wide invitation to tender for the individual construction works began in February 2009. As a direct preliminary construction work , the construction department felled the trees in Heckenstallerstraße.
Implementation of the construction work
The first construction phase began in August 2009 with the clearing of the construction site. Then the directional lanes were relocated to the north.
The second construction phase began in autumn 2009. In the second construction phase, the southern bored pile walls were built, the pre-excavation of the ceiling pit was carried out and the 1.2 meter thick tunnel ceiling was erected. The traffic runs on the northern provisional lanes. At the end of the second construction phase, the ceiling pit was backfilled. The third construction phase began with the relocation of the eastern carriageway to the south side. Then the central pillar was built with a bored pile foundation. In the next step, the middle area of the tunnel ceiling was produced and then backfilled.
In the fourth construction phase, the western carriageway was relocated to the south, the bored pile walls were installed, the tunnel ceiling was constructed and the construction site was backfilled. Construction phase 4 was completed in 2014.
The last construction phase began with the excavation under the ceiling elements. Then the shell construction followed. This work took place from mid-2012 to mid-2014. This was followed by the technical interior work from the beginning of 2014 to mid-2015. The Heckenstallerstraße tunnel was opened on July 27, 2015.
Expansion on the surface
In the western section of Heckenstallerstraße, noise barriers were built and the Grabbebrücke was rebuilt. There is no longer any surface traffic above the tunnel. The Heckenstallerpark was opened here in 2017 .
Cost of the project
The costs of the "Mittlerer Ring Südwest" construction project with Garmischer Strasse and tunnel, Luise-Kiesselbach-Platz and Heckenstallerstrasse and tunnel as well as the various entrances and exits amounted to € 398 million.
Technology in the tunnel
The 620 meter long tunnel has an operating structure with a pumping station and two emergency exits to the surface. The exhaust gases from the vehicles are blown out in the direction of travel at the tunnel portals. If there is sufficient movement, they are transported by the wind generated by the traffic itself; large fans switch on when necessary, especially in the event of a long-term traffic jam.
Remarks
- ↑ The stated costs are the total costs of the project Middle Ring Southwest
- ↑ In the referendum, the Munich CSU politicians were supported by the FDP , the Munich Chamber of Commerce , the Chamber of Crafts and the ADAC .
