Abstract

Research purposes: The shanghai － Nanjing expressway is an important traffic artery． The factors of the bridge function，landscape and vehicle driving would be considered in the design of Line 1 of Wuxi metro crossing the Shanghai － Nanjing expressway while the feasibility of the bridge crossing the expressway also could be considered． As the key project of Wuxi，a feasible design scheme can get good social and economic benefits．

Research conclusions: This paper analyzes the advantages and disadvantages of the steel girder，continuous girder and steel truss girder，compares the advantages and disadvantages of all schemes in the fields of the construction difficulty，influence on the traffic and engineering cost etc，and determines to use the continuous girder bridge by rotation construction，which is the most suitable bridge type for this project． This scheme satisfies the track usage conditions with eatures of the small influence on the traffic，low engineering cost，simple construction and a little maintenance cost，having good social and economic benefits．
