Construction will lead to the closure of part of Route 785 in the St. George area starting Tuesday, Aug. 3.
The Department of Transportation and Infrastructure says crews will be installing a precast concrete box culvert at the Mill Lake Outlet.
Traffic will be diverted along Red Rock Road and Route 770 during the closure, which could last up to three weeks.
Once the culvert is installed, the road will be re-opened with intermittent partial lane closures for guiderail installation, riprap replacement, and the restoration of Route 785.
