In road and highway construction a gore (or nose in modern British English) is a triangular plot of land (as designated 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 designated incidentally when two surveys failed to meet. Etymologically it is derived from gār, meaning spear.
A theoretical gore is commonly marked with transverse or

painted lines (much as traffic island
A traffic island is a solid or painted object in a road that channels traffic. It can also be a narrow strip of island between roads that intersect at an acute angle. If the island uses road markings only, without raised curbs or other physical ...

s. These help separate drivers on the mainline from those entering and exiting the highway, and also aid the latter category of drivers in regulating their speed while accelerating and decelerating. Gores at exit ramps occasionally feature impact attenuator
An impact attenuator, also known as a crash cushion, crash attenuator, or cowboy cushion, is a device intended to reduce the damage to structures, vehicles, and motorists resulting from a motor vehicle collision. Impact attenuators are designed to ...
s, especially when something solid follows the theoretical or physical gore, such as a bridge abutment
An abutment is the Bridge#Structure type, substructure at the ends of a bridge Span (architecture), span or dam supporting its Bridge#Structure type, superstructure. Single-span bridges have abutments at each end which provide vertical and l ...
.
At the "theoretical gore point," a dotted white line becomes a wide solid white channelizing line and another wide solid white line angles off along the edge of the diverging road, forming an elongated white triangle in front of the gore. This as a "neutral area" with white chevron markings optionally added.

*Intersection (road)
An intersection or an at-grade junction is a junction where two or more roads converge, diverge, meet or cross at the same height, as opposed to an interchange, which uses bridges or tunnels to separate different roads. Major intersections a ...
