Abstract
P & Z Method is the cantilever erection system with a long erection girder for prestressed concrete bridge, and has various merits campared with traditional systems. For example, we can easily and safely build a long span bridge over a river without temporary jetty. We describe how to erect Tsukiyono Oohashi, the first experience in Japan using P & Z Method, and the new measurement system to control of up-bending for cantilever erection bridge by micro computer.
