One of WGK’s main duties as the County Engineer in Franklin County is the replacement of 100-year-old timber bridges that carry rural, gravel roads through the Homochitto National Forest, which takes up around 80 percent of the county. The timber bridge over Brushy Creek on Bill Arnold Road finally failed, and WGK designed an SAP project to replace it with a poured-in-place concrete bridge. In addition to the bridge, the site required numerous drainage improvements, erosion control and bank stabilization.
- Approximately 13,200 cubic yards of excavation and borrow material.
- Installation of 168 linear feet of reinforced concrete drainage pipe.
- Installation of 724 tons of rip-rap and 1,400 square yards of geotextile matting.
- Construction of a 200 linear-foot poured-in-place concrete bridge, requiring 995 linear feet of 40-foot and 80-foot prestressed concrete beams and 37,600 pounds of reinforcement.
- Application of 10 tons of agricultural limestone and fertilizer for 5 acres of erosion control.
- Total Project Cost: $697,000.
