Johnson School Road Bridge over Davis Creek
This project will replace the 21-foot long timber and concrete bridge on Johnson School Road at Davis Creek with a new single span concrete structure.
The existing bridge is showing signs of deterioration, primarily due to the bridge beams being continually submerged since the bridge is located upstream from a local reservoir. In addition, the existing horizontal curve near the approach of the bridge along with its narrow width results in larger vehicles often crossing over the centerline due to the higher travel speeds of the roadway.
List of planned improvements
- Replace bridge over Davis Creek with a longer wider bridge built above the flood plain.
- Install abutment and approach retaining walls, as needed, to minimize impacts to wetlands.
- Construct the bridge to 40-feet wide, to include two travel lanes and shoulders.
- Add a water quality treatment system for roadway storm water run off.
In addition, this project will salvage 85-foot long concrete girder bridge beams from another county bridge project. Recycling the beams will benefit the environment and result in an overall cost-savings.
Please note: This bridge replacement project will require a 3 month road closure. Click on "Closures" to the right for more details.
