The Missouri Department of Transportation will close the intersection of Hwy. B at Hwy. 21 in Hillsboro from July 31-Aug. 2, weather permitting, so crews may replace a culvert at the intersection.
Detour signs will direct motorists to use Old Hwy. 21 to bypass the closure.
The work had been scheduled for July 17-19, but was postponed due to stormy weather predictions.
