Corridor Alignment, Slew Bridge Structural Design, and Safety Mitigation Modeling
This project involved the schematic design of 7,900 linear feet (L.F.) of a four lane divided roadway, planned as an ultimate six lane divided major thoroughfare. The structural scope includes a custom 400 ft long bridge spanning Slayer Creek.
Alignment & Stakeholder Coordination: Establishing a definitive schematic alignment required intensive communication between proposed developments, longtime existing landowners, and the City. Working directly with these parties, BHC analyzed several alternative options to successfully arrive at a mutually preferred alignment corridor.
Floodplain & Structural Engineering: Along the preferred alignment, a custom bridge over Slayer Creek crossing at a skewed angle had to be schematically designed. Collaborating with a structural engineer, BHC aligned the structure with the proposed right-of-way alignment using offset piers and abutments. This engineered solution ensured minimal geometric impact on the surrounding floodplain boundaries.
Design Speed Safety Mitigation: After working with all project stakeholders, BHC determined that the point of connection between the proposed roadway and the existing roadway did not satisfy safe design criteria due to a severe mismatch between the design speed and the posted speed of the legacy roadway. BHC coordinated this friction point with the County and presented several engineering options to safely correct the safety conflict before construction phases.
