The Querverschub of the 2,000-ft Oberkassel Bridge

Abstract:

In 1976 West German bridge engineers undertook the moving of the largest structure ever moved in one piece and in such a short period of time. The Oberkassel Bridge connecting Dusseldorf and Oberkassel across the Rhine River was built 156 ft (47.5m) upstream from its final designated position. This constructed position was necessary since traffic requirements dictated the use of the obsolete bridge while the new bridge was under construction. After dismantling of the old bridge and the downstream extension of the substructure of the new bridge, the new bridge was pulled downstream to the alignment of the old structure. Keeping the old alignment was absolutely necessary to minimize environmental impact on the two cities. The new cable-stayed steel box girder bridge was slid on teflon bearing pads on a polished stainless steel track. The lateral movement of the bridge (Querverschub in German) required only two days (13 hours).
