The scope of work for this structure location included the removal of the existing four span single track TPG-BD x 115'-0" bridge, as well as an attached siding structure which was no longer in service. The substructure consisted of cast-in-place abutments and precast back walls and wing walls. The structure itself was a single span TPG-BD x 188'-0" and was erected offline on temporary structures. Substructure work included the construction of concrete drilled shafts at each abutment to allow future expansion of the State Road below. This project was phased work and required the installation of jump spans to allow the substructure and abutments to be installed without affecting train movements. Once the substructure and cast-in-place abutments were completed and the new TPG-BD was complete, the structure was rolled into place on Hillman rollers and set on the bearings. Work schedule and critical path items were completed ahead of schedule and did not affect any train schedules.
