This paper briefly introduces the choice and design and force analysis of bridge type&structure size for the prestressed concrete continuous rigid frame bridge. This bridge has adopted the prestressed concrete continuous rigid frame bridge with main span of 85 m. A variable section box girder with single box and single chamber was adopted for the main girder of the main bridge with three - way prestresssing system, rectangular thin - walled hollow pier and bored pile foundation was adopted for substructure of the bridge. Each parts of this bridge meet standard re- quirements by analysing structure for the bridge, and the safety properties are better of this bridge. This paper sum- marizes main points of this bridge design for giving some reference to related technical personnel.
