Définition et Signification de "divided highway"

What is a "divided highway"?

A divided highway is a road that has a physical barrier separating the lanes of traffic going in opposite directions. This design helps to prevent head-on collisions and keeps traffic moving in a safer, more organized manner. Divided highways are commonly used for high-speed routes, such as major roads, expressways, or freeways, and are typically wider than regular roads to accommodate more lanes of traffic. The separation between lanes helps improve traffic flow and reduces the risk of accidents.
