Highway 111 North near Lewis Chapel Road in Sequatchie County was closed by the Tennessee Department of Transportation late Monday afternoon.
Pipe failure is to blame for what looks like a sinkhole across the roadway.
Weather permitting, TDOT is hoping this will be a short time closure. Crews are working to reopen the roadway (right shoulder) to carry one lane of traffic by the end of the week.
Until those efforts are completed, drivers will detour the area using the SR 111 Flat Top Mountain exit, travel north on SR 304 (Jones Gap Road), turn left onto SR 305 (Lewis Chapel Road), then turn right returning to SR 111 North. Signage is posted directing drivers around the closure.
