Road Closed
The St. Charles County Highway Department will close Dietrich Road between Entrance Court and Dumont Court, weather permitting, on Monday, March 18, 2019, to allow for removal and replacement of a deteriorated culvert.
Traffic will be required to use a detour route around the closure for approximately five days starting at 7:30 a.m., Monday, March 18, and ending at 3 p.m., Friday, March 22. Local traffic can access either side of the closure location, but no through traffic will be permitted. Signs notifying motorists of the closure and necessary detours will be posted.
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.
