Long-Term Vegetation Management Strategies for Roadsides and Roadside Appurtenances
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.
