Interstate Drive Phase II

St. Charles County Transportation Projects

Interstate Drive Extension Phase II:

The St. Charles County Highway Department along with contractor Kuesel Excavating Inc. are in the process of completing a new roadway that will connect existing Interstate Drive at Route Z to the existing Quail Ridge Parkway (I64 Outer Road). This project is designed to construct a two lane roadway with six foot shoulders and a ten foot multi-use path. The project will allow Wentzville residents better access to Quail Ridge Park and secondary access to I64. The project will have minimal impacts to existing Route Z other than the construction of a signalized intersection.

The project also includes the construction of upgrades to existing features inside Quail Ridge Park primarily a new round about intersection. Quail Ridge Park will remain open during construction, but may have minor detours and temporary lane restrictions during specific operations.
