MOUNT OLIVE -- Work is scheduled to begin Monday on the U.S. 117 and Country Club Road interchange project just north of town.
Motorists can expect delays and lane closures during construction.
When completed, U.S. 117 will pass over Country Club Road.
Work has been underway since August on a new interchange at U.S. 117 and O'Berry Road, Dudley.
O'Berry Road was closed in October and could remain closed for up to a year as work crews continue construction of an overpass to take the road over U.S. 117 South.
Both interchanges are scheduled for completion by October 2019, with additional work including vegetation and reforestation possibly continuing through March 2020.
The two projects will cost an estimated $20.6 million.
The interchanges are being built to enhance safety and in preparation for U.S. 117 eventually being designated as an Interstate in this area, state Department of Transportation officials said.
Both intersections already carry an average of 15,000 vehicles per day, and that number is expected to increase to more than 27,000 per day by 2037, according to DOT data.
