This research investigated the overhang and shear capacity of a precast overhang system for potential use during the construction of bridges with precast overhang panels. The research was performed in three phases: the Phase 1 research including work specifically for the Rock Creek Bridge in Parker County, Texas; the Phase 2 research for general precast overhang panels, and; the Phase 3 research investigating the shear capacity. Grout material characteristics were also assessed for possible use in the haunch; constructability issues were also addressed
