2. On what types of roadways does your agency install shoulder rumble strips?
|
From page 242... ...
• As a general rule we do not install shoulder rumble strips on both sides of the road, however, in the case of a two-lane road being converted to one direction of a divided highway there can end up being rumble strips on both shoulders. • On a freeway, the strips are continuous on both shoulders of each roadway.

Shoulder rumble strips are not installed within urban areas, where there is curb and gutter, where the posted speed limit is 45 mph or less, across bridge approaches /decks, or adjacent to guardrail if the clear path between shoulder rumble strip and guardrail is <5 ft.
