The Pförtchenbrücke is a road bridge which in Erfurt the Flutgraben of Gera spans. The building, which has been a listed building since 1981, is called the most beautiful bridge in Erfurt.
The Pförtchenbrücke was built in 1897 as part of the flood ditch construction with two lanes and footpaths on both sides in order to open up the lower Dichterviertel of Löbervorstadt and to connect it with the city center. The name refers to the Erfurt fortifications, which next to the bridge had a defensive tower, called the "Stumpfe Turm", with a small passage and a subsequent footbridge over the fortress moat. The connection, known locally as the gate, enabled pedestrians to get directly to the Dreibrunnenfeld and the Steigerwald.
The arch bridge was built with a width of 12.72 m between the parapets and a clear width of 24.5 m. The arch has the shape of a basket arch with a combatant thickness of 0.9 m and a crown thickness of 0.77 m. In the actual brick vault, which is supported on concrete abutments , 118,000 bricks, 25,000 of which are yellow hard-fired clinkers, were processed in a cross bond. Light Seeberger sandstone was used for facing the wing walls, front walls and vaulted forehead . The gate bridge was decorated with four obelisks and two cast-iron candelabras and three - dimensional decorative elements such as coats of arms on the front walls. The parapets, cornices and obelisks are made of greyish Arenshausen sandstone.
The bridge was completed in early 1898. From 1899 to 1904, a ring line of the Erfurt tram ran over the structure. The federal highways 4 and 7 crossed the Pförtchenbrücke until 2006.
In 1988 the four bridge obelisks were renovated. An extensive repair of the bridge structure followed between 1997 and 1998. In addition to crack grouting and needling in the vault and abutment area , the exposed masonry of the front and wing walls as well as the parapets were restored using stone restorations.
