Interstate Drive - Phase 4

This project will provide for a new Interstate Drive connection from Hepperman Road to the existing portion of Interstate Drive to the west. Proposed improvements include:

  • New 2-lane road with standard 12-foot lanes and 6-foot shoulders.
  • Full-depth shoulders to allow for future widening/expansion of Interstate Drive.
  • Construct a new 10-foot multi-use path along the south side of the road.
  • Widen for left turn lane at Hepperman Road.

The project is fully funded by the St. Charles County’s ½-cent Transportation Sales Tax. The engineering design consultant is AECOM. The project is estimated to cost approximately $2.4M.
