Map with all coordinates: The Gmünder Einhorn-Tunnel (working title for the construction phase: Christine-Tunnel ) is an approximately 2.2 km long tunnel of the federal highway 29 (B 29) through Schwäbisch Gmünd . It consists of a driving tunnel with two lanes and a rescue tunnel, which is connected to the main tunnel by six escape tunnels.
Names
Until construction began, the Gmünder Einhorn Tunnel had no official name. During their construction period, tunnels usually bear the first name of the tunnel godmother , in the case of Schwäbisch Gmünd the wife of the then Lord Mayor Wolfgang Leidig , which is why the tunnel was initially called Christine-Tunnel . After the completion it got its new name. In the population, the name Salvatortunnel was temporarily established after the pilgrimage site of St. Salvator above the tunnel . The media mainly talked about the Gmündertunnel or the B29 tunnel, although other names such as Lindenfirsttunnel were also discussed. In the summer of 2011, the city of Schwäbisch Gmünd carried out an online survey about the most suitable name in the opinion of the population of Gmünd. The name Bud Spencer Tunnel was also an option ( Bud Spencer once stayed in Gmünd as part of a swimming tournament) and was supported by a Facebook initiative that publicized the unusual proposal across Germany and even generated international media coverage. At the end of July, however, the Gmünder local council decided against this name and postponed the decision. Instead, the municipal outdoor pool in the Schiessal is now called Bud Spencers. When the name was finally decided at the end of October 2011, the majority of the city council voted in favor of the name Gmünder Einhorn-Tunnel, based on the coat of arms of the city of Schwäbisch Gmünd .
history
When the B 29 was expanded in 1975, discussions arose in Schwäbisch Gmünd about the course of the route in the city. In 1980, the tunnel idea, a tunnel in the valley, concrete, but more detailed plans have been repeatedly rejected for various reasons, so it was not until 1989 to a concrete draft came in a 1996 planning approval process passed, the very next year, existing power gained. Construction of the first construction phase began in 1998, the second followed in 2006. Also in 2006, a further planning approval procedure for the 1.6 kilometer long rescue tunnel was started, which has been final since May 2007. After the start of the mining work in autumn 2008, the tunnel breakthrough occurred on February 27, 2011. A citizens' initiative, "Initiative Pro Tunnelfilter", campaigned for an exhaust air filter to be installed in the Gmünder Einhorn Tunnel. To this end, a citizens' dialogue was started in March 2012. The renovation of the defective extinguishing water pipe led to further delays in 2013. The tunnel was cleared on November 25, 2013, among others with the Federal Transport Minister Peter Ramsauer and the State Winfried Hermann .
Others
There is usually a maximum speed of 80 km / h in the tunnel. This speed limit can be changed using variable message signs . Monitoring is carried out by infrared light ("black flash technology").
The construction costs for the Gmünder Einhorn-Tunnel amounted to over 280 million euros. This makes the tunnel currently the most expensive bypass in Germany.
