Avoid the intersection of McNaughton Avenue and St. Clair Street in Chatham on Thursday.
Municipal officials say some turns will be prohibited, and some thru-traffic will be diverted.
Westbound traffic on McNaughton will be forced to turn right onto St. Clair and follow a posted detour route.
Northbound traffic looking to turn west onto McNaughton from St. Clair won’t be able to.
This will be in effect from 7 a.m. to 3 p.m. on Thursday, as crews work to adjust manhole cover frames on the roadway’s surface.
