The Oder Valley Bridge is located in the southern Harz between the districts of Barbis and Bad Lauterberg in the Göttingen district and was built in 2009–2012 as part of the relocation of the B243 . Since it crosses the FFH area “Sieber, Oder, Rhume”, both a special construction and a construction procedure were necessary.
construction
The structure has a total span of 496 m and overcomes a height difference of around 26 m between the abutments. The maximum height of the carriageway above ground is around 25 m. A challenge in the bridge construction was the crossing of the floodplain forest in the Oder lowlands, which is protected as an FFH area , as well as the neighboring ravine forest on the steep slope, in which no bridge piers are allowed. Temporary use of FFH areas is also not permitted due to adverse effects during construction. The last bridge span (end span) of the bridge before the abutment on the mountain side therefore spans the floodplain forest with the Oder and the ravine forest with a span of 103 m, while the other eight spans are between 35 and 77.5 m. The assembly of the end field was carried out without assembly support. The semi-arches had to be assembled in a cantilever with auxiliary anchoring. The gaps in the superstructure steel boxes were closed with a mobile crane from the abutment on the mountain side. 3,364 t of structural steel were used for the bridge, 1,023 t of reinforcing steel and a concrete volume of 4,668 m³ for the deck girder, 500 t of reinforcing steel and 3,940 m³ of concrete volume for the substructures.
