freeway systems
Interconnected expressway grids
Freeway systems are networks of high-speed, limited-access highways designed to move traffic through metropolitan areas without stopping.
The term emphasizes interconnection—multiple freeways linking to form a unified transportation grid: The Los Angeles freeway system is notoriously congested.
Urban planners discuss freeway systems when considering how routes interact, where interchanges fall, and how the whole network serves a region.
