Curb ramps must be placed to enable a person with a mobility disability to travel from a sidewalk on one side of the street, over or through any curbs or traffic islands, to the sidewalk on the other side of the street.

Because each curb ramp is unique, careful thought and planning must go into their design and construction. Use the guidelines below to comply with PROWAG requirements when selecting which type of curb ramp should be used and when deciding upon location. 1. Consider the whole intersection. 1. Locate the pedestrian access route(s) for the sidewalk(s)...
Whenever possible, use the same curb ramp design at each quadrant in the intersection. Sometimes consistency is not possible and multiple designs are necessary. Keep in mind that the design which falls lowest in the design hierarchy should never serve as the controlling option. For example, if one corner requires a depressed corner because of site ...
Pay careful attention to existing surface drainage conditions when designing and then building curb ramps. Debris and water diminish a curb ramp’s usability. The curb ramp and gutter connection should (1) prevent water from ponding at the base of the ramp and (2) impede debris accumulation. Ensuring that the ramp and sidewalk have positive drainage...
Edge protection on both sides of the ramp is a raised surface at least 2 inches (50 mm) high. A minimum clear width of 36 inches (915 mm) is provided between handrails and the edge protection. A lower railing is shown parallel to the ramp mounted no higher than 27 inches (685 mm) above the ramp.
Sidewalks form the backbone of the pedestrian transportation network. According to the Institute of Transportation Engineers, Technical Council Committee 5A-5 (1998), sidewalks "reduce the incidence of pedestrian collisions, injuries, and deaths in residential areas and along two-lane roadways."
A landing at least 36″ long at the top of curb ramps provides room to approach or exit ramps and turn without encountering compound slopes of flared sides. Side flares are intended mainly to prevent tripping hazards.
Jul 25, 2019 · ADA Ramp Landing Requirements. Landings are required at the top and bottom of each ramp run. Ramp landings cannot have a slope greater than 1:48. The ramp landing width should be as wide as the widest ramp run leading to the landing.
Several measures to aid persons with disabilities may be applied at an intersection and to the entire sidewalk network. Perhaps most notable are curb ramps, detectable warning surfaces, and accessible pedestrian signals at signalized intersections.
