R&E’s scope of work included preparation of design PS&E and Construction Management for the federally funded replacement of the Main Street culvert at Fishtrap Creek.  The existing culvert was removed and replaced with a 96-foot single span bridge structure using precast concrete girders, cast in place bridge deck and supported on cast in place concrete pile foundations.  Other work also included structural earth walls, utility underground conversion, water, sewer and storm drainage improvements, as well as decorative street lighting. Particular design challenges included a channel skew of 45 degrees to the roadway and high potential for headcut upon removal of the existing culvert which could have an effect on channel bank stability up and downstream of the project.  Additionally, Main Street is a major east/west arterial street which drove a tight construction sequence and timeline. The project was funded with FHWA – ER money.
