What is defined as a transverse roadway connecting separate roadways of a divided highway?

A transverse roadway connecting separate roadways of a divided highway is identified as a crossover. This term specifically refers to a designated path or route that allows vehicles to move from one side of the divided highway to the other, enabling traffic to switch between the opposing directions safely.

In contrast, an overpass refers to a road or bridge that crosses over another road or railway, generally designed for the purpose of allowing uninterrupted flow of traffic. An access road typically connects a main road to local developments or properties, providing drivers with entry and exit points. An intersection is a point where two or more roads meet or cross but does not specifically imply a connection across divided roadways. Therefore, the term crossover most accurately describes the type of roadway specified in the question.
