Mileage and Travel - Terminology


Route Classification - Priority ranking for highways in Kansas.

A - Interstate Highways, including the Kansas Turnpike

B - Routes that serve as the most important statewide and inter-state corridors for travel. The routes serve distinct trip movements since they are widely spaced throughout the State. On major sections of the routes traffic volumes are relatively constant. A significant number of out-of-state vehicles use Class B, and trips are typically very long.

C - Defined as arterials, these routes are closely integrated with Class A and B routes in service to all parts of the State. Major locations that are not on an A or B are connected to them by a C route. Average trip lengths are typically long.

D - These routes provide access to arterials and serve small urban areas not on a higher-class route. These routes are important for inter-county travel.

E - Primarily for local travel, these routes typically carry short trips. Class E routes are used to connect rural residents with other routes or to provide access to small towns in the area.
