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 at the intersection with 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

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 physica ...

An abutment is the substructure at the ends of a bridge span or dam supporting its superstructure. Single-span bridges have abutments at each end that provide vertical and lateral support for the span, as well as acting as retaining walls t ...

In the US, 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 ar ...
