What type of highway is defined as having partial control of access?

The type of highway characterized by partial control of access is the expressway. This means that the expressway allows some access points, such as intersections and driveways, while also having sections with limited entry and exit points to help maintain higher speeds and improve overall traffic flow. The combination of controlled and uncontrolled access can help manage the interaction between local traffic and long-distance travel.

Expressways are designed to facilitate efficient transportation while still accommodating some level of traffic entering and leaving the roadway system. This partial control helps to minimize the number of conflict points compared to fully accessible roads, thereby improving safety and traffic movement.

In contrast, a beltway typically refers to a road that encircles a city or metropolitan area and may serve different access patterns, while a thruway generally implies a highway designed for longer-distance travel with limited access points. Meanwhile, interstates are part of the National Interstate Highway System and have full control of access, designed to connect major cities with minimal interruptions.
