roadhighway

roadhighway is a term that generally refers to a major public road, typically designed for high-speed vehicular traffic. The primary function of a roadhighway is to connect distant locations efficiently, facilitating the movement of people and goods across significant distances. These routes are often characterized by multiple lanes in each direction, divided by a median or barrier, and feature limited or no at-grade intersections. Instead, access is usually controlled through interchanges such as ramps and overpasses, minimizing disruptions to traffic flow.

The design of roadhighways prioritizes safety and speed. They are engineered to handle large volumes of traffic and are built to withstand heavy loads. Pavement surfaces are typically made of asphalt or concrete, and speed limits are generally higher than on local roads. Signage is crucial for navigation, providing information on destinations, distances, and upcoming exits. Roadhighways can be part of national, state, or provincial road networks, and many are toll roads, where users pay a fee for their use. The development of roadhighways has been instrumental in modern transportation, enabling trade, tourism, and personal mobility on a large scale.
