Bridgework engineering

Competition Rhein Bridge, L 202 Schweizer Straße, Hard - Fußach

Project Description:
The existing deck bridge will be replaced by a newly constructed bridge with an unmistakable appearance. The extensive framework conditions, such as the depressed construction height for road connections and bicycle traffic, river engineering and flood-related conditions in accordance with the international Rhine-River Regulatory Act, extremely difficult soil conditions, as well as the strict adherence to a budget and high quality goals was accomplished with the elected bridge concept. The asymmetric cable-stayed bridge with a support span length = 39.5 + 135 + 43 + 39.5 = 257 m features a hybrid support structure with composite-peloton and pre-stressed concrete end-panels in hollow and/or full panel cross-sections. The backcourts form an integral bridge. The great width of the bridge at 19.4 m posed a challenge to the pylon form-finding. The high-level design requirement of flowing and dynamic shapes was achieved while adhering to economically feasible construction methods.
