The Krämpfertorbrücke is a road bridge which in Erfurt the Flutgraben of Gera spans. The listed bridge was built in 1895 with a brick vault and widened in 1998 with a reinforced concrete vault .
The Krämpfertorbrücke was built in 1895 as part of the flood ditch construction in the area of a former city gate in Erfurt's east-west axis in order to open up the Krämpfervorstadt and to connect it with the city center. The arch bridge was m with a width of 13.6 and 25.0 m built inside diameter within six months. As a static system, the arch has the articulated support line arch with the shape of a segment of a circle with a transom thickness of 1.3 m and a vertex thickness of 1.03 m. In the actual brick vault, which is supported on abutments made of 500 m³ of concrete, 142,000 burnt-on bricks and 26,000 yellow hard-fired clinkers were processed in a cross bond. For the facing of the front walls and the parapets, sand-lime bricks were used. The building was opened to traffic on December 15, 1895. From 1904 to 1916 a tram route ran from Anger to Leipziger Strasse over the bridge.
Between 1998 and 1999 the Krämpfertorbrücke was repaired and expanded. The structure was widened from 13.6 m to 19.4 m for a new light rail line from the Anger to the Ringelberg residential area . This was done on the southern side by adding an approximately 5.8 m wide reinforced concrete arch bridge, the abutments of which were founded on 84 injection piles . The abutments of the old bridge were grouted with cement due to their porosity . Seeberger sandstone was used for the cladding of the reinforced concrete bridge and any natural stone renovations . The construction costs amounted to four million Deutschmarks .
On October 4, 1999, the Krämpfertorbrücke was opened to traffic again. Since then, it has been moving 2.35 m wide sidewalks with mosaic pavement on both sides, a 1.5 m wide cycle path on the south side, two 6.2 m wide lanes to the east and the 6.3 m wide track of light rail line 2 into one Integrated lane towards the city center.
