The Petueltunnel is a road tunnel in Munich . The Petuelring runs in the tunnel . The tunnel is part of the Middle Ring and has a length of around 1,500 meters. It was opened on July 6, 2002 after a five-year construction period.

location

The Petuel Tunnel is located about four kilometers north of Munich city center. The tunnel runs in a west-east direction, consists of two tubes and, in addition to the main portals, has the exits and entrances to Knorrstrasse / Belgradstrasse (east direction) and Leopoldstrasse (west direction). There is a side tunnel in the east, which leads directly to the A 9 . The course of the tunnel marks the border between the districts of Milbertshofen and Schwabing-West .

course

Coming from the Olympiapark , the western tunnel portal is on Petuelring, immediately west of Schleißheimer Straße . Two main tubes, each with two lanes, lead eastwards. After 600 meters, another lane from Knorrstrasse / Belgradstrasse joins the tunnel as an entrance (east direction) and exit (west direction). After 500 meters, the exit (east direction) and access (west direction) branches off Leopoldstrasse. In an easterly direction of travel there is a side tunnel that leads to the A 9 towards Nuremberg / Berlin .

In the main tunnel, Schenkendorfstrasse begins under Leopoldstrasse . The Petuel Tunnel ends about 100 meters to the east. A 250-meter-long glass enclosure connects to the east. Schenkendorfstrasse continues in the direction of Bogenhausen .

history

First plans

At the beginning of the 1980s under the CSU Mayor Erich Kiesl , the Petuel Tunnel project was well advanced. These first plans for the construction of the Petuel Tunnel were stopped in 1990. This was due to the result of the local elections at the time. Since the Green Party was against the expansion of the Middle Ring, the tunnel construction project was postponed.

Referendum

Supported by the FDP , IHK Munich , Chamber of Crafts and ADAC , some CSU politicians launched the first Munich referendum entitled “The Middle Ring needs three tunnels”. On June 23, 1996, the Munich voters decided with a narrow majority for a further expansion of the Middle Ring and against the will of the city council majority made up of the SPD and the Greens.

New plans

After the referendum, planning for the tunnel was resumed. Since the tunnel planning had already progressed well before the construction stop, construction work could already begin in 1997.

Construction of the tunnel

The Petuel Tunnel was built by Max Bögl and Ed. Züblin AG established. First the trees were felled in the construction site area. The tunnel was built using the top-down method. Here, the later roof of the tunnel is built first. In the second step, the actual tunnel will be built underneath. Due to the requirement to keep at least three lanes open in each direction of travel, the lane had to be swiveled numerous times.

On October 31, 2001, a lane of the tunnel was opened to the public between Knorrstrasse / Belgradstrasse and the driveway to the A 9. This enabled space to be created in the eastern part of the construction site.

Opening of the tunnel

On July 6, 2002, Lord Mayor Christian Ude and the then Minister of Education and Cultural Affairs Monika Hohlmeier opened the tunnel. Traffic was opened on the same day at around 12:15 p.m.

Further expansion on the surface

By 2004 the surface above the tunnel was redesigned. The western part between Schleißheimer Straße and Knorrstraße / Belgradstraße was converted into a four-lane street without lane separation. The eastern part up to Leopoldstraße was converted into Petuelpark without any traffic. The Petuelpark opened on June 27, 2004.

Cost of the project

The construction of the Petuel Tunnel, including the dismantling of the surface, amounted to DM 400 million (approx. € 205 million).

Technology in the tunnel

The Petuel tunnel is equipped with modern safety technology. The safety of the tunnel is constantly monitored by the Munich traffic control center. Freely programmable lines of text on the tunnel portals can alert drivers to dangerous situations or special conditions in the Petuel tunnel.

In addition to a sprinkler system, there are also transmission stations for six radio stations in the tunnel . The traffic control center can use these channels to make announcements in particularly dangerous situations. The exhaust air from the tunnel is disposed of via an exhaust air chimney that is attached to the Riesenfeldstrasse bunker .

Speed ​​limit and control

The maximum speed allowed in the main tubes was initially set at 60 km / h. Since the number of accidents in the tunnel was high, the speed limit was reduced to 50 km / h in 2004. Since December 2015, a standard speed limit of 60 km / h has applied again on both sides. The speed limits are controlled with a traffic control system using LED signs. When traffic is high, the speed limit is usually reduced to 40 km / h. Since the end of June 2014, compliance with the speed limit has been checked for both directions by a black light flash system.

Special events

So far there have been no major incidents in the tunnel. In an ADAC test in 2003, the tunnel received the grade good . There were only deficits in the legibility of the signage. However, this was improved by the state capital.

First Petuel tunnel

As early as 1963 a structure was called the Petuel Tunnel. It was the tram underpass of the then line 8 between the stops Rümannstrasse and Keferloherstrasse, which crossed under the Petuelring in a north-south direction. The line last served by tram lines 12 and 13 was closed in 1993. During the construction period of the current road tunnel, the structure was still used as an entrance for the construction vehicles and then backfilled.

Transmission information

In the Petueltunnel you can receive all common Munich local stations and the traffic radio from Antenne Bayern via the frequencies of the Olympic tower via a small receiver transmitter . The public broadcaster Bayern 3 is also available in the tunnel. Also DAB radio stations of the channels 5C, 11C, 11D and 12D sent in the tunnel.
