Long-term vegetation management strategies that decrease the need for routine chemical and mechanical vegetation control can reduce recurring maintenance costs, highway worker exposure to traffic, impacts to the environment and cultural resources, and maintenance-related delays to the traveling public. However, these strategies vary in their effectiveness, longevity, initial construction costs, maintenance requirements, and aesthetic values.
The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 350: Long-Term Vegetation Management Strategies for Roadsides and Roadside Appurtenances presents information on strategies that control the establishment and growth of roadside vegetation over an extended period, reducing the need for herbicides, mowing, and other mechanical controls.
Supplemental to the document are a Selection Tool, a Factsheet, and a Presentation.
