(KNZA)--A milling and overlay project has begun on K-16 Highway in Jackson County.

The project covers about 13 miles, from Wisconsin Avenue in Holton to the Jackson/Jefferson county line.

 According to the Kansas Department of Transportation, 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 and add extra time in their travel schedules.

Work will take place Monday through Saturday, during daylight hours.

 Herzog Contracting of St. Joseph, Mo., is the contractor on the $1.5 million project.  The project is expected to be complete in late September, weather allowing.
