Road frontage refers to the area of land between the front boundary of private property and the edge of the carriageway, but excluding any drain. In real estate, frontage is the width of a lot, measured at the front part of the lot. Frontage roads, on the other hand, are local roads running parallel to a higher-speed, limited-access road, often used to provide access to private driveways, shops, houses, industries, or farms. Frontage roads give indirect access to abutting property along a freeway, either preventing the commercial disruption of an urban area that the freeway traverses or allowing commercial development of abutting property. In commercial real estate, frontage may be described as ‘front foot’ . All lots in a city must have some sort of frontage to allow access to the property.
