The tunnel supporting mountain is a railway - tunnel of Nuremberg-Erfurt high-speed railway of 500 m length with miter . The tube lies between the route kilometers 150.743 and 151.243. It crosses under the 588 m high Großer Tragberg and therefore bears his name.

The planning and construction of the section between construction kilometers 67.2 and 68.2, in which the tube is located, was put out to tender by Deutsche Bahn in May 2007 across Europe. The double-shell tube was built using the shotcrete method . In addition to the tunnel, three railway overpasses of eight, 13 and 16 meters in length were built. The earthworks had a volume of 113,000 m³. In addition to a landfill, construction roads with a length of around 600 m and a rainwater retention basin with a volume of around 120 m³ were built. The tunnel excavation consisted of excavation and blasting from north to south. The excavated material was temporarily stored on a landfill about 300 m from the south portal. Together with the excavated material from the Lohmeberg and Brandkopf tunnels , the material was later used to fill the Thiemtal opencast mine ( 50 ° 38 ′ 48 ″  N , 10 ° 56 ′ 27 ″  E ).

The planned construction period was between November 2007 and July 2009. In July 2008, completion of the shell was expected for September 2009. At the beginning of 2008 the earthworks took place on the edge of the future tunnel. The piercing should take place in August 2008, the tunneling should be finished in March 2009. Concreting should start in April of the same year. The actual tapping took place on November 18, 2008. Petra Heß , Member of the Bundestag, took over the sponsorship of the tunnel . After noise measurements showed that the permissible limit was exceeded at night, since mid-January 2009 it has only been possible to blow up during the day. The tunnel was ceremoniously broken through on May 8, 2009. Work on the tunnel lasted until September 2010. In January 2011 the project was completed.

The total investment is around 14 million euros. A Thuringian company was commissioned.
