The Mainz autobahn tunnel is a road tunnel on the Mainzer Ring of federal autobahn 60 in the Mainz district of Hechtsheim . The tunnel consists of two tubes with three lanes each. It was built between 2006 and 2012.

Building

Since its complete completion at the beginning of August 2012, the tunnel has one tube in each direction with a length of 357 meters and three lanes each. At the time of its opening, its technical equipment complied with the latest safety requirements at the time.

The walls of the tunnel were made of 1.2 meter thick and up to 36 meter long reinforced concrete piles. To this end, 22,500 linear meters of large bored piles were installed . The tunnel ceiling is 1.5 meters thick and has a total area of ​​6540 square meters.

The use of materials during construction amounted to 50,000 cubic meters of concrete / reinforced concrete and 750 tons of steel. The asphalt surface is 85,000 square meters and the new noise barriers 5200 square meters.

The structure has an operating building with an uninterruptible power supply . The extinguishing water tank has a volume of 72 cubic meters.

history

Starting point and planning

Before construction began, the Bundesautobahn 60 around Mainz, also known as Mainzer Ring , consisted of two lanes in each direction and had no hard shoulder, as the route was originally built in the 1950s and 1960s as a new building on Bundesstraße 9 and became a federal freeway in the 1970s was upgraded.

The traffic load increased over the years and the structural situation of the autobahn was no longer sufficient for the traffic needs. On this occasion, something should also be done for noise protection , as the motorway in this section of the route leads past the Mainz districts of Hechtsheim and Oberstadt on a dam. The erection of noise barriers would not have provided sufficient relief in this area.

From 2001 the Mainzer Ring between the Mainz-Süd motorway junction and the Weisenauer Bridge was expanded. First, the lanes between the Mainz-Süd motorway junction and the junction (22a) Mainz-Hechtsheim West (Messe) were widened, and the Weisenauer Bridge was upgraded so that these sections of the route can have three lanes in each direction.

construction

Both directions were on the southern runway between 2006 and 2008. The northern runway was dismantled during this time.

Construction work started on August 28, 2006. On August 4, 2008, the first tunnel was opened to traffic, and on July 11, 2012, both tunnel tubes were open on two lanes. On August 10, 2012, all three lanes in both tunnel halves were finally released.

The construction was divided into three sections:

  1. West pre-cut: Lowering by approx. 0 to 11.5 m over a length of 700 meters.
  2. Tunnel: Lowering from approx. 11.5 to 12.7 m at 450 meters.
  3. Pre-cut east: lowering of approx. 12.7 up to 0 m at 1050 meters.

In August 2006, all traffic was first relocated to the lane in the direction of Rüsselsheim ( 4 + 0 traffic routing ), and then the lane in the direction of Bingen between the junctions (22a) Mainz-Hechtsheim West (Messe) and (23) Mainz-Weisenau over twelve Meters were removed and the north tube, using the so-called cover construction , could be erected. For this purpose, the junction (22b) Mainz-Hechtsheim Ost at the flyover of Geschwister-Scholl-Straße was completely closed. After a year or so, this first tunnel was broken on August 1, 2007. After completion of the north tube (direction Bingen) a party was celebrated in the tunnel on July 20, 2008. The Rhineland-Palatinate transport minister, Hendrik Hering , announced that the two-kilometer route would cost 75 million euros, of which 58 million euros were used to build the tunnel. Furthermore, by then a total of around 900,000 cubic meters of excavated earth will have been moved, 50,000 cubic meters of concrete and 10,500 tons of steel have been built. The excavated earth was backfilled in the nearby Mainz-Weisenau quarry.

Asphalting work on the north tube on July 16, 2008

After a fire brigade exercise, this tube was opened to traffic in the direction of the Mainz-Süd motorway junction on August 4, 2008. Shortly afterwards, the oncoming traffic was also relocated to the same tube so that the remaining surface carriageway could be removed in the same way and the south tunnel built. Originally it was planned to do this by the end of 2010, in autumn 2010 the completion date was postponed to the beginning of 2012. When the asphalt work began in July 2011, spring 2012 was given as the completion date. In June 2012 the opening for July 2012 was announced. A second open tunnel day took place on July 1, 2012. After further finishing work, both tunnels and the Hechtsheim-Ost junction were opened to traffic at the beginning of August 2012. The official ceremony took place on Friday, August 10, 2012.

Since the completion of the first section of the tunnel, Geschwister-Scholl-Strasse (Landesstrasse 425) has not been crossed over, but under crossed; the street has been 1.10 meters above its old level since then. The same applies to the motorway bridge over Alte Mainzer Straße (Kreisstraße 9), which has been crossing the motorway since 2008 instead of going under it; for this, the course of the road was raised by 2.10 meters.

Height difference between the old motorway and the new tunnel at the Hechtsheim-Ost exit (2012)

The Hechtsheim-Ost junction remained completely closed until it was released in August 2012 and is one of the few motorway entrances and exits that are in a tunnel.
