In the US, “freeway” typically refers to a toll-free, high-speed road with limited access, while “highway” is a broader term for any major public road.
Freeway Vs. Highway
A freeway, as defined by the Federal Highway Administration (FHWA), is a divided highway with access-controlled ramps and full control of vehicular traffic movements. Freeways are designed to facilitate faster and uninterrupted travel, typically allowing for higher speed limits. They are often characterized by their multiple lanes, overpasses and underpasses, and limited points of entry and exit.
A highway is a general term used to describe a public road that connects various destinations. Highways can encompass a wide range of road types, including two-lane roads, multi-lane roads, and even freeways. Unlike freeways, highways may have traffic lights, intersections, and driveways, making them not fully access-controlled.
What is a Freeway?
A freeway is a type of road or highway that is designed for high-speed, uninterrupted traffic flow. It is characterized by the following features:
- Controlled Access: Freeways have controlled access, which means they typically have on-ramps and off-ramps at designated points. This allows for smooth traffic flow and limits direct access to adjacent properties.
- Divided Lanes: Freeways have multiple lanes that are divided by a median or barrier. This separation helps in managing traffic and reducing the risk of head-on collisions.
- No At-Grade Crossings: Unlike other roads, freeways do not have at-grade crossings such as intersections or traffic lights. Instead, they use interchanges to facilitate the movement of vehicles between the freeway and intersecting roads.
- Higher Speed Limits: Due to their design and controlled access, freeways typically have higher speed limits compared to other types of roads.
- Restricted Access: Freeways often have specific restrictions, such as prohibiting certain types of vehicles (e.g., bicycles or pedestrians) from entering.
- Long Distances: Freeways are designed to cover long distances, connecting cities, regions, or states.
- Designed for Higher Traffic Volume: Freeways are built to accommodate a large volume of traffic, including passenger vehicles, trucks, and buses.
- Managed by Transportation Authorities: Freeways are typically managed and maintained by transportation authorities or government agencies responsible for ensuring their safety, efficiency, and upkeep.
Freeways are designed to provide efficient and safe transportation for high-speed, long-distance travel, while minimizing disruptions and improving traffic flow.
