Highway

A highway (also known as freeway, superhighway, expressway, or motorway (British English)) is a multi-lane road designed for high-speed travel by large numbers of vehicles.

Freeways have high speed limits, multiple lanes for travel in each direction, and a large separation (either through distance or high crash barriers) between the lanes travelling in opposite directions. Crossroads are bypassed using underpasses or overpasses, and entries and exits are limited in number and designed so as to ensure that vehicles do not disrupt the traffic as they enter or leave the freeway. Freeways do not usually have traffic lights.
