This document discusses different types of pre-stressed concrete bridge construction techniques. It describes full pre-stressing and partial pre-stressing methods as well as different pre-stressing patterns like axial and eccentric. Several pre-stressed concrete bridge types are listed including cast in place post-tensioned box girder bridges, precast spliced I-girder bridges, and precast segmental span by span bridges.
