City of Bridgeton

Cochran performed the surveying, geotechnical study, hydraulic analysis, engineering design, and special construction inspection/administration for this federal aid bridge replacement; bridge no. 05300111, on Gist Road in the City of Bridgeton.  The project included a single span structure (82’) that utilizes the more efficient NU 35 girders.  The scope of the project included clearing and grubbing, removal of improvements, excavation, embankment in place, asphalt pavement, removal of the bridge, type 2 rock blanket, slab on concrete girders, open concrete barrier curb, pre-stressed concrete girders, reinforcing steel, construction signs, and restoration.  Since this project was federally funded, all construction documents were required to meet standards for project delivery as outlined in MoDOT’s Local Public Agency (LPA) manual.  Cochran performed special inspection services in collaboration with City staff.
