The Kohlbrand Bridge across the River Elba - Hamburg • Federal Republic of Germany

Abstract

The suspension bridge, in the port of Hamburg, is one of the most important engineering works in northern Germany. The work is divided into three sectors: 1) The eastern accommodation ramp, 2,410 m long. 2) The bridge across the river bed, 520 m long. 3) The western accommodation ramp, -,050 meters. The bridge is 17.60 m wide and has four traffic lanes. Sectors 1 and 3 were solved by means of prestressed concrete superstructures, with one or two cell box girders. Sector 2 has a 325 m span between the two piers and a 54 m high and 150 m ship passage. The central piers that rise 130 m above the ground consist of a base of reinforced concrete and a 98 m high metallic part, formed by a box of bolted and subsequently welded beams. In the upper part of this last part are the connections for the suspension cables for the overhanging part of the bridge. The construction works were carried out beginning with sectors 1 and 3 on both sides of the river simultaneously. Once these were completed and the piers were raised, the work.
