Design of long span modular bridges for traffic detours

[摘要] (cont.) The pylon is balanced with an anchoring cable and ideas for modular foundations for the anchor are presented. A span of approximately 183m is possible for a 3 lane bridge limited by the maximum axial tower capacity and 250m for the 2 lane bridge based on lateral vibrations. The design fully reflects modularity and should promote the use of modular bridges for longer span crossings.
