freeway system
Interstate road grid
A freeway system is a network of high-speed, limited-access highways serving a metropolitan area or region.
The term usually refers to interconnected routes that allow drivers to travel across urban areas without stopping for traffic signals: The Los Angeles freeway system is notoriously congested during rush hour.
Major systems typically include numbered routes, interchanges, and on-ramps designed for continuous traffic flow.
