Abstract
This bridge joins to Hamburg-Hannover and the Hamburg-Lubeck roadways. It is 411 m long, 30.74 m wide, and has five spans. The main span is 172 m long, and is suspended by cables from two towers, rising 53 m above the bridge pavement. The stiffening; structure of this suspended span consists of a central box and two lateral full web girders, with a uniform depth of 2 ms. The towers support two sets of cables, which rest on supports situated at unequal heights with respect to each other. These supports are so arranged that thermal deformations shall not be excessive nor cause large secondary moments. Most of the bridge elements have been manufactured in the workshops and taken to the site by river transport. The main span has been built by successive overhangs, till the two sides have met together at the crown.
