A sidewalk (American English) – also known as a footpath, footway or pavement in Australian English, New Zealand English, 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. In some places, the same term may also be used for a paved path, trail or footpath that is not next to a road, for example, a path through a park.
