(KNZA)--A milling and overlay project is scheduled to begin on U.S. 159 in Atchison and Brown counties on Thursday, July 15, weather permitting.

The Kansas Department of Transportation says the work will cover about 16 miles, from the northern city limit of Effingham to the southern city limit of Horton.

KDOT says traffic will be restricted to one lane in the work zone and will be directed by a pilot car, flaggers, signs and cones. Drivers should plan for delays of up to 15 minutes.

Work will take place Monday through Saturday, during daytime hours. The project is expected to be completed by mid August.

Herzog Contracting of St. Joseph, Mo., is the contractor on the $1.9 million project.
