The Schönebecker Elbauenbrücke is a road bridge that spans the Elbe northeast of Schönebeck at river kilometer 310.5. As part of the re-routing of the federal highway 246a , the building with an 8.0 m lane width with two lanes connects the federal highway 14 Halle – Magdeburg with the East Elbe areas and relieves the inner-city old Elbe bridge as part of the Schönebeck bypass . The bridge structure, which cost EUR 31.6 million net, was opened on August 27, 2013. The forecast traffic load is 13,120 vehicles / 24h.
construction
The bridge between the Elbe dykes spans the Elbe and the Elbe meadows with a total length of 1128.5 m. It is divided into a 309 m long foreland bridge on the south side and one 330.5 m long on the north side. Separated by expansion joints, the 489 m long river bridge lies in between, the main opening of which is designed as a single-hip cable - stayed bridge with an A-shaped 73 m high pylon standing on the left bank of the Elbe. This bridge section has eight openings with a prestressed single-web T-beam cross-section and spans of 32.25 m, 4 × 37.50 m and 3 × 40 m. The ninth field above the Elbe spans 183.50 m and has a relatively light, single-cell, 2.0 m high composite steel cross-section as a roadway girder . It is carried by nine fan-shaped pairs of cables, the cables of which consist of seven-wire prestressing steel strands . The pylon is again anchored using nine pairs of cables in the three adjacent side panels.
Up to the merging point of its shafts, the pylon is a reinforced concrete structure, 3.50 m thick and 2.50 m wide in the transverse direction of the bridge and with a box-girder cross-section above the roadway. In the area of the rope anchorages there is a composite cross-section with an inner steel box girder.
The approach bridges, made of prestressed concrete , are curved in plan and have the continuous beam as a structural system in the longitudinal direction . The southern structure has eight fields with spans of 32 m, 44 m, 34 m, 39 m, 42 m, 42 m and 32.25 m, the northern spans of 34.25 m, 6 × 43 m and 36.25 m . In the transverse direction there is a single-web, 11.6 m wide T-beam with a height of 1.8 m.
Construction work
The pre-stressed concrete foreshore bridges were built with a telescopic arm. This was followed by the cable-stayed cantilever assembly of the current field of cable-stayed bridge with a truck-mounted crane . The first sections were delivered by ship.
Naming
On May 16, 2013, the Schönebeck city council decided in a special meeting that the bridge should be named Schönebecker Elbauenbrücke . The daily newspaper Schönebecker Volksstimme previously started a survey in which the readers took part.
Structural Award 2014
The Institution of Structural Engineers honored the bridge and its planners Leonhardt, Andrä and Partners with the Structural Award 2014 in the category "Highway or Railway Bridge Structures" in London on November 14, 2014 . It won one of the world's most prestigious civil engineering awards in front of the Shenyang Hun River Ribbon Bridge in China.
Justification of the Institution of Structural Engineers for the choice of the best bridge structure in the world in 2014: “The jury is impressed by the simple elegance of the bridge, which fits perfectly into the surrounding landscape. It creates a real landmark ”.
