The St. Charles County Highway Department is extending the closure of westbound and eastbound Treetop Drive between Ivy Court and Country Club Road until July 29 due to weather. Work began June 21 on removal and replacement of deteriorated concrete pavement in the area and was originally scheduled to be complete July 8.

Traffic is required to use an alternate route around the closure while the concrete is replaced. Signs notifying motorists of the closure and necessary detours are posted. The detour route includes portions of Treetop, Greenleaf and Sundowner drives, and Country Club Road.

This road project is part of a continuing effort by St. Charles County Government to improve the County’s road system for the safety of the travelling public.
