The Luise-Kiesselbach-Tunnel (Tunnel Garmischer Straße) is a 1530 meter long road tunnel in the southwest of Munich . Together with the Heckenstallerstrasse tunnel , it is part of the Mittlerer Ring Südwest project . The lanes in the north direction were released on July 27, 2015, the south direction was opened on July 28, 2015. Like Luise-Kiesselbach-Platz, the tunnel was named after the women's rights activist and social politician Luise Kiesselbach .

location

The tunnel is located in the Sendling-Westpark district around five kilometers southwest of the city center. It runs in a north-south direction, crosses under Garmischer Strasse , Luise-Kiesselbach-Platz and Heckenstallerstrasse and ends in the north just before the slip road to the A 96 and in the south after the junction with Murnauer Strasse.

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 already fully planned. At the coalition negotiations on red-green in Munich's 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 under the stipulation that low-vibration technology was used during construction and that construction times were observed, as well as the use of evidence preservation procedures. In the areas where the tunnel is immersed in the groundwater, water management issues must be taken into account.

The tunnel construction was originally supposed to start in 2005.

Construction progress

General

Bored pile device 2012 on Heckenstallerstraße

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.

From mid-2009, the building department set up an information container on the square to inform the public.

Tunnel services

The entire "Middle Ring Southwest" project was divided into five construction lots. The area of ​​the A 96 in Garmischer Strasse represents construction lot A. This construction lot is followed by construction lot B from the future northern tunnel entrance to Luise-Kiesselbach-Platz. Luise-Kiesselbach-Platz itself is construction lot C.

In October 2007, the canal and branch relocations began . On the west side of Garmischer Strasse in the area of ​​Westpark, Waldfriedhofstrasse and Krüner Strasse, the supply lines (gas, water and sewage) were relocated. At the same time, from the end of 2007, the plans for the construction and the provisional traffic management were drawn up. The Europe-wide invitation to tender for the individual construction works began in February 2009. From March 2009, the construction department felled the trees in Garmischer Strasse.

Construction work

The first construction phase began in August 2009. The three-lane lanes in each direction of travel were swiveled to the east of Garmischer Strasse in order to make room for the construction site. Then the western bored pile walls were driven into the ground.

The second construction phase began in autumn 2009, the third in February 2011.

In the second construction phase, the western bored pile walls were constructed, the ceiling pit excavated and the 1.2 meter thick tunnel ceiling erected. The western company buildings were built in the shell. The traffic ran on the eastern 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 southern carriageway to the west side. Then the central support with a bored pile foundation was created. In the next step, the middle area of ​​the tunnel ceiling was built and then backfilled.

The last construction phase began with the excavation under the ceiling elements. Then the shell construction followed. This work was completed on schedule by mid-2014. This was followed by the technical interior work from the beginning of 2014 to mid-2015. The Garmischer Strasse tunnel was opened earlier than planned on July 27, 2015. After commissioning in 2015, the surface was rebuilt by 2018.

Opening of the tunnel

Opening ceremony of the tunnel on July 25, 2015

On July 23, 2015, around 1,500 participants took part in the six-kilometer public tunnel run . The official opening followed on July 25, 2015. Here Lord Mayor Dieter Reiter , Bavaria's Interior Minister Joachim Herrmann and other politicians symbolically cut a ribbon. On Luise-Kiesselbach-Platz there was a big town festival with live music and for a few hours the people of Munich also had the opportunity to explore the tunnel on foot. A tunnel beer garden and a café were set up below. Numerous information boards worked out the building history in detail. It was opened to traffic on July 27th and 28th.

Expansion on the surface

The above-ground sections of Garmischer Strasse were adapted to the reduced traffic volume (3,000 to 5,000 vehicles per day) by 2017. At the end of June 2016, a ramp was completed that improves the connection between the tunnel and Murnauer Straße.

The wide median in Garmischer Strasse has been upgraded to a median promenade with a gravel path, tree-lined avenues and massive barriers opposite the roadway . The area of ​​Luise-Kiesselbach-Platz was greened. The Heckenstallerpark is located with an area of ​​2.75 hectares above the Heckenstaller tunnel.

Cost of the project

The costs of the “Mittlerer Ring Südwest” construction project with Garmischer Strasse, Luise-Kiesselbach-Platz, Heckenstallerstrasse, tunnels and various entrances and exits amount to 398.5 million euros.

Technology in the tunnel

Speed ​​measurement, fans and emergency stop bay

The 1530 meter long tunnel has three operating structures with a pumping station. Eleven emergency exits lead to the surface. The exhaust gases from the vehicles are blown out in the direction of travel at the tunnel portals. In the tunnel there are stationary measuring devices for speed monitoring with photo cameras and video cameras for monitoring the flow of traffic. The cameras in the emergency bays are equipped with automatic image recognition. As soon as a vehicle comes to a stop in the bay, the image of the camera in question is switched to a large screen in the traffic control center.

Remarks

  1. The stated costs are the total costs of the project Middle Ring Southwest
  2. In the referendum, the Munich CSU politicians were supported by the FDP , the Munich Chamber of Commerce , the Chamber of Crafts for Munich and Upper Bavaria and the ADAC .
  3. Forecast traffic figures for 2015. They come from the expert opinion for the planning approval from 1999, prepared by Professor Kurzak.
