PIKEVILLE, Ky. (WMDJ) — The Kentucky Transportation Cabinet’s District 12 office says nighttime sweeping will begin this week across all four-lane corridors in Eastern Kentucky.

Crews will work from 7 p.m. to 7 a.m., sweeping travel lanes, medians, and barrier walls. The mobile operation will move county by county, beginning in Lawrence County, then progressing south through Johnson, Martin, Floyd, Knott, Pike, and wrapping up in Letcher County.

Drivers can expect moving lane closures, rolling slow-downs, and equipment working in the roadway overnight. KYTC says the sweeping work will continue for the next month or two, depending on weather conditions.

Officials are asking drivers to use caution, slow down, and stay alert for workers after dark. The district says the effort is meant to improve visibility, drainage, and roadway safety as crews clear debris from heavily traveled routes across the region.
