Cape Girardeau Special Road District required a new bridge over CR643, Cape Rock Drive, at its intersection with CR645 which entailed roadway and bridge design along with construction administration. Bacon Farmer Workman (BFW) took on the new bridge project. The old bridge was unique in that it was trapezoidal in shape with one end being wider to accommodate a turning movement at the intersection. BFW designed the new bridge to be more economical while maintaining high safety and structural performance along with accounting for the abutment and wingwall design. To achieve this, the new designs allow for:
- Bridge:
- Standard dimension precast beams
- Additional width across the bridge matching the approach nearest the intersection
- Abutment and Wingwall:
- A range of conditions in the quality of rock in a small area
- Avoided unnecessary impact to existing features like utilities, streambanks, rock formations, and limited right of way
In total, the construction cost was $712,000. BFW is proud to have successfully standardized the bridge design for easier repairs and material sourcing while also avoiding excessive impacts on the surrounding area.
