Class I two-lane highways are categorized as what type of road?

Class I two-lane highways are categorized as major arterials because they serve a critical role in the transportation network by facilitating the movement of traffic over longer distances. These highways typically connect larger urban areas and provide access to key destinations, acting as the primary routes for higher volumes of traffic.

Major arterials are designed to support mobility rather than direct access to properties along the road, allowing for higher traffic speeds and reduced congestion. Their design often includes features that accommodate a higher level of service, such as fewer intersections and more efficient traffic flow.

This classification is distinct from local roads, which primarily provide access to homes and businesses; minor arterials, which serve more localized traffic needs; and collector roads, which link local roads to major arterials while also providing access to adjacent properties. Thus, the classification of Class I two-lane highways as major arterials reflects their importance in the broader transportation system.
