Interstate Drive (Phase I)
Informational Virtual Open House
This project involves proposed improvements along Interstate Drive from Quail Ridge Park to the intersection of Prospect and Duello roads, including:
- Widening the existing roadway and adding paved shoulders to provide safer travel and an improved driving surface.
- Improving drainage facilities and sight distance along the corridor.
- Adding pedestrian accommodations from Duello and Prospect roads to Quail Ridge Park.
- Upgrading the intersection at Prospect and Duello roads with a roundabout to improve traffic flow and accommodate continued expansion along the corridor.
The estimated $3.9 million project is funded by the St. Charles County 1/2-cent Transportation Sales Tax, as well as the Federal Highway Administration (FHWA). Oates Associates, Inc., is serving as the design engineering consultant.
Phase I is the final of a five-phase construction plan along Interstate Drive. Phase II included improvements from Quail Ridge Park to Route Z. Phase III included improvements from Route Z to Hepperman Road. Phase IV will extend Interstate Drive from its terminus just east of South Point Prairie Road to Hepperman Road and is currently in the right-of-way acquisition phase. Phase V connects Interstate Drive to the new David Hoekel Parkway west to Schaper Road and was completed in December 2020.
Preliminary plans have been approved by MoDOT. Work is underway on right-of-way plans. Once plans have been completed, they will be sent to MoDOT for review and approval to begin right-of-way acquisition. Acquisition likely will begin in summer 2021.
