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

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

Hall Brothers, of Marysville, is the contractor on the $1.7 million project.  The project is expected to be complete by late August, weather permitting.
