In road and highway construction, a gore (US) or nose (UK) is a triangular plot of land, not to be driven on, where a road forks at the intersection with a second road, or merges on and off from a larger one. Gores at exit ramps occasionally have impact attenuators, especially when an obstruction such as a bridge abutment follows the gore.
The US term gore (describing a space) historical, representing a characteristically triangular piece of land, often designated incidentally when two surveys failed to meet. Etymologically it is derived from gār, meaning spear.
