Roadside Vegetation Management

Guardrail Herbicide Program

The Pollution Prevention and Compliance Program oversees compliance on VTrans’ herbicide permit. The management of weeds and unwanted vegetation is an important element of roadside maintenance. The Vermont Agency of Transportation’s decision to manage vegetation on, under, and behind guardrail using herbicides is truly one of economics. When you compare the time and resources necessary to address this vegetation control issue with mowers and hand labor the costs far outweigh that resulting from the use of herbicides.  VTrans has approximately 1,000 miles of guardrail (year 2011 estimate) which needs constant inspection, replacement, repair and maintenance. For more information on our herbicide program please read: Why We Spray Guardrail.
