Abstract
An upper structure for a bridge includes a coping placed on the top of a pier, and girders held by the coping, wherein the coping has girder holding grooves. The girders are installed continuously without using bridge bearings. The coping and the girders behave in an integrated state. The girders are held by being fitted into the grooves, so the coping is not excessively exposed to the outside. The girders and the coping are dry joined together in a prestressed state using prestressed steel strands. Further, the girders and the coping can be integrated with each other without being processed by site work.
