Construction of six mainline bridges and one two-span overpass
Mosites Construction’s work for The Pennsylvania Turnpike Commission on section 55A1 of Pittsburgh’s Southern Beltway featured six mainline bridges and one two-span overpass. The project included a pair of three-span concrete girder bridges to carry mainline SR 576 over Raccoon Creek, which required roughly 1500 cubic yards of concrete to construct the four pier caps. Mosites worked closely with Independence Excavating Inc. to develop and execute a schedule that allowed for both structural and excavation work to proceed simultaneously to complete the project within the strict timeframe.
