This project will upgrade the intersection at Central School Road and St. Peters-Howell Road to improve traffic flow and reduce congestion during peak traffic periods and to improve safety and pedestrian access. Proposed improvements include:
- Widening St. Peters-Howell Road to provide for dual southbound left turn lanes.
- Widening Central School Road to provide for a second lane in each direction.
- Rebuilding the traffic signal and providing ADA-compliant pedestrian facilities.
The project is funded by St. Charles County’s ½-cent Transportation Sales Tax and with Federal Highway Administration (FHWA) Congestion Mitigation and Air Quality (CMAQ) Improvement Program funding. The engineering design consultant is HR Green, Inc. and the project is estimated to cost approximately $1.8M.
