Gore (road)

In road and highway construction a gore (or nose in modern British English)[1] is a triangular plot of land (as created when a road forks when intersecting a second road, or merges on and off from a larger one). A "virtual" (or "theoretical") gore is a triangular shaped space, characteristically marked off with distinguishing highway paint, often found leading to the unpaved area of a larger physical gore.

The term "gore" (describing a space) is a historic one, representing a characteristically triangular piece of land, often created incidentally when two surveys failed to meet. Etymologically it is derived from gār, meaning spear.[2]

A theoretical gore is commonly marked with transverse or chevron painted lines (much as traffic islands) at both entrance and exit ramps. These help keep drivers already on and those entering and exiting the highway separate, and aid the latter in regulating their speed accelerating and decelerating. Gores at exit ramps occasionally feature impact attenuators, especially when something solid follows the theoretical or physical gore, such as a bridge abutment.
