Which characteristic is NOT associated with expressways?

Expressways are designed to facilitate high-speed traffic flow and to enhance safety by reducing potential conflicts between vehicles. Characteristics commonly associated with expressways include high-speed limits, no cross traffic, and the presence of medians that separate lanes of traffic.

The feature that is not typically associated with expressways is roadside retail access. Unlike local roads, which often have businesses and intersections spaced closely together, expressways are constructed to minimize points of entry and exit. This design helps prevent disruptions in traffic flow and reduces the risk of accidents caused by vehicles accessing roadside services. Expressways aim to maintain continuous and uninterrupted movement, making roadside access impractical and unsafe. Thus, the absence of roadside retail access is a defining characteristic that distinguishes expressways from local roads or highways.
