New York City Department of Transportation (NYC DOT) has developed a program dedicated to upgrading and installing pedestrian ramps and is committed to making our pedestrian space safe and accessible for all road users.
The term corner refers to intersection corners (space on the sidewalk at the intersection of two streets), midblocks (a crossing that is not at an intersection, usually in between two streets), tops of T-shaped intersections, medians or islands (a small section of raised concrete in the street). A corner can have one or more ramps.
