(KAIR)--A mill and overlay project is underway on a 12-mile stretch of U.S. 73 Highway between Atchison and Leavenworth.

The Kansas Department of Transportation says the project will take place from north of Millwood Road in Leavenworth County to south of Ravenhill Drive in Atchison County.

Work began in early October and is scheduled for Monday through Saturday from 6 a.m. to 6:30 p.m.

During work hours, KDOT says traffic will be restricted to one lane and controlled by flaggers and a pilot car operation. Motorists may face delays of up to 15 minutes and should be prepared to slow down and stop.

Traffic will be also controlled using portable digital message signs, arrow boards, signage and traffic cones.

Herzog Contracting Corporation, of Kansas City, Mo., is the contractor for the $2.2 million project, which is expected to be completed in mid-November.
