Abstract
The main parts of the approach bridges of Sutong Bridge are of twin prestressed concrete continuous girder bridges with spans each 75 m of constant cross sections and six lanes on the carriageways,and the superstructures of the parts of the bridges were erected by precast segmental assembling construction method.In this paper,the design alternatives,principal components and construction sequences of the TP75 overhead launching gantry used for the segmental assembling of the bridges are described.
