The Kansas Department of Transportation is starting a mill and overlay project on U.S. 400 in Labette County.

The work begins at the Montgomery-Labette county line and continues east for approximately 9 miles, ending at the concrete highway pavement. Flaggers and a pilot car operation will direct one-lane traffic through the work zone during daylight hours. Drivers can expect delays of 15 minutes or less. The road work should be completed by late April, weather permitting.
