(KAIR)--Shoulder work on an area highway will mean delays for motorists.  

According to the Kansas Department of Transportation, the placement of rock on the shoulders of K-4 Highway, from U.S. Highway 24 to K-92 Highway, will begin Monday.  

The work will affect both Jefferson and Shawnee counties.  

Traffic will be reduced to one lane, and controlled by a pilot car, through the seven-mile work zone.  

Traffic will be affected from 9 a.m. to 3 p.m. weekdays, with 15 minute delays expected.

Motorists are encouraged to allow extra time for travel.  

The project is expected to be complete by Friday, July 12, if weather allows.
