location

The Carl-Ulrich-Brücke is a bridge between Offenbach am Main on the left and Frankfurt-Fechenheim on the right bank of the river. It is named after Carl Ulrich (1853–1933), who lived in Offenbach for a long time and was the first President of the People's State of Hesse .

history

Ship bridge at Isenburg Castle (1819)

Until 1819 there was only one connection between the Offenbach and Fechenheim banks of the Main, with boats called Schelch , which operated near the Offenbach town center at Isenburg Castle .

The first bridge between Offenbach and Fechenheim was a ship bridge inaugurated in June 1819 . It was on the Schloßstraße (Offenbach) and Starkenburger Straße (Fechenheim). An important reason for building the bridge was to bypass customs in Frankfurt. The Grand Duchy of Hesse (Offenbach am Main) and Kurhessen ( Fechenheim ) were already part of the German Customs Union , which the Free City of Frankfurt only reluctantly joined in 1835. This was the first Main Bridge between the two Hessian states.

Offenbach-Fechenheim Main Bridge (1887)

In 1887, one kilometer downstream, the Offenbach-Fechenheim Main Bridge was built and the ship bridge dismantled. It was a steel arch bridge, the superstructure of which was replaced by a wider steel structure in 1934. In the spring of 1945, Wehrmacht pioneers blew up the building. After the war, the provisional reconstruction of the Offenbach-Fechenheim Main Bridge took place in 1947 as one of the first Main bridges to be restored in the Frankfurt area.

In 1952/53 the temporary structure was replaced by a steel bridge after a renovation. The structure was a beam construction with 6.45 meters clearance at the highest navigable water level. The superstructure rested on the two abutments and five pillars that were taken over from the previous bridges. The six openings had spans of 37.80 meters, 40.10 meters, 41.10 meters, 40.10 meters and 37.80 meters. The width of the bridge was 13 meters. The road surfaces were renewed in 1977 in a construction period of five weeks. The Hessian State Office for Roads and Transport declared in July 2008 that after several further repairs, the bridge was now in need of renovation so that a new construction would be cheaper. In September 2010 the structure was closed to vehicles with a gross vehicle weight over 7.5 t in both directions. It only had a usage permit until the end of 2014 and had to be blocked in the event of prolonged low temperatures.

Carl Ulrich Bridge (2014)

On November 15, 2012, the groundbreaking ceremony for the new replacement building with a larger opening for shipping took place. After a munitions clearance, during which 7000 tank shells were found, among other things, the foundation work began seven months late in autumn 2013. At the end of April 2014, the steel trough in the middle section of the new bridge was floated in and set down on auxiliary piers next to the old bridge on the eastern side. In November, the old bridge was demolished with the help of a dredger and then the new bridge was moved transversely to its final position and the road connections were made. It was opened to traffic on December 4, 2014. The construction costs of around 17 million euros, not including the cost of recovering ordnance, were borne half by the State of Hesse and the federal water and shipping administration. The total contract value for the construction company was around 12.6 million euros.

The bridge superstructure of the girder bridge, which is around 234 meters long and 14 meters wide, is a steel composite structure . It has a haunched , single-cell, open steel trough and a reinforced concrete deck connected with head bolt dowels . The structure system consists in the longitudinal direction of a three-span continuous beam with spans of 60.86 meters in the peripheral fields and 112.04 meters in the central main field.

Traffic importance

The bridge over the Main bend is the only road connection over the Main between Frankfurt-Fechenheim and Offenbach am Main in the area of ​​the Offenbach core city. In addition to the two-lane state road L 3001, it also crosses two footpaths and cycle paths. In addition, the RMV bus lines F-41 and 551 and the night bus lines n62 and n63 cross the building.
