Question from Jill


Does adding a crosswalk constitute an alteration and require curb ramps with detectable warnings?


Yes, newly constructed or altered streets, roads, and highways must contain curb ramps or other sloped areas at any intersection having curbs or other barriers to entry from a street level pedestrian walkway. Whether detectable warnings (raised truncated domes) are required is more complicated. If U.S. Department of Transportation funding is involved detectable warnings are required.
