SC STATE PEDESTRIAN BRIDGE

Orangeburg, South Carolina

FME provided geotechnical services for a new South Carolina State University pedestrian bridge that spans over US 21/US 178 and a creek adjacent to the roadway. The bridge consists of a single span, prefabricated steel truss. To facilitate pedestrian access on and off the bridge, there is a system of ramps at each end of the bridge. The ramp system consists of an intricate pattern of ramps using mechanically stabilized earth (MSE) construction. The ramps were constructed over an array of vertical drains that were installed to mitigate seismic-induced liquefaction.

FME performed a subsurface exploration and laboratory testing and developed bridge foundation and retaining wall design recommendations for the project.
