Freeway divisions, also known as highway lanes, are the sections of a freeway that are separated by physical barriers such as guardrails or concrete dividers. These divisions are designed to keep traffic flowing in an orderly manner and to reduce the risk of collisions. The number of lanes on a freeway can vary depending on the amount of traffic it carries. Generally, freeways have at least two lanes in each direction, but some may have up to six or more.
