As spring approaches, Kentucky’s transportation crews will soon begin roadside treatments targeting invasive and harmful vegetation to prevent infrastructure damage and maintain roadway visibility.
KYTC is directed to control invasive plants and noxious weeds in accordance with state statutes.
Noxious weeds like Spotted Knapweed and Canada Thistle often invade and destroy the roadside turf grass, leaving these areas vulnerable to erosion.
Aggressive invasive species like Kudzu can smother native plants through rapid reproduction and long-term persistence. Some of these plants are a favorite of white-tailed deer and attract wildlife closer to roadways.
Kentuckians with noxious weeds on private property adjacent to state-owned rights of way may request highway crews to treat listed vegetation.
Application forms are available upon request from the appropriate KYTC highway district office. Contact information may be found on the district web pages.
Motorists are reminded to use extra caution when crews are out treating roadsides.

- Amur Honeysuckle (Lonicera maackii)
