Freeway vs. Expressway — What's the Difference?

Freeway and expressway are terms frequently utilized in the realm of transportation, especially in the context of road infrastructures designed for rapid and unobstructed travel. However, nuances differentiate the two, mainly hinging on their design, access, and regulation features.

In contrast, expressways may or may not be toll roads. They are designed to expedite travel, yet might still include occasional intersections controlled by traffic lights, especially in urban areas. Some expressways also allow for direct property access, something not seen on freeways.

A freeway, as the name suggests, generally offers "free" passage, meaning there are no tolls to pay. Its primary characteristic is the uninterrupted flow of traffic. This is achieved by the exclusion of traffic lights, intersections at grade, or property access points. Instead, the freeway makes use of overpasses, underpasses, and interchanges to ensure continuous movement. A common sight across the United States, the Interstate System is an exemplar of freeway infrastructure.

Both freeway and expressway are purposed to minimize congestion and ensure safer, faster travel compared to regular streets. However, the extent of their accessibility and the presence or absence of intersections or tolls draw a line between the two.
