A sidewalk (American English) – also known as a footpath, footway or pavement in Australian, New Zealand, Irish English, South African English and British English – is a path along the side of a road. A sidewalk may accommodate moderate changes in grade (height) and is normally separated from the vehicular section by a curb. There may also be a median strip, or road verge (a strip of vegetation, grass or bushes or trees or a combination of these, referred to as either a verge or a nature strip in Australia, and as an island in parts of the United States) either between the sidewalk and the roadway or between the sidewalk and the boundary.
