Answer:
Step-by-step explanation:
Landscaping along roads is a way to blend the concrete roadway into the surroundings as well as a way to manage the environmental qualities of the road. Growing plants near roads slows, absorbs, and cleans water runoff. Thus, plants along roadsides reduce soil erosion, control flooding, and result in cleaner water supplies. Plants for roadside landscaping also act as snow fences, keeping the snow from drifting into traffic.
