This is a proposal for standardized road classifications in Kansas as part of a larger discussion about classification standards nationwide (United States/Highway classification). You're free to add on and edit the contents of this page.


We use several different metrics to evaluate the importance of every highway. These include, but are not limited to:

  • Traffic counts
  • Road quality for motor vehicles (e.g. number of lanes, average speeds, pavement)
  • Number and quality of alternate routes available
  • Whether the roads connect any populated locations of note or serve popular recreation areas

We do not copy any of the governmental ways of classifying highways (functional class, US vs state vs county route, etc.), but we do use them as guides to help with the particulars.

Proposed Guidelines

(These guidelines will be temporary. In the future, more specific guidelines will be developed for Kansas)


The top category, highway=motorway should only be applied to roadways that are either signed Interstate highways or have ALL of the following characteristics:

  • Grade separation
  • Limited access via on/off ramps
  • No at-grade intersections or traffic signals (although on-ramps may have traffic control devices)
  • Divided carriageways
  • Designed and maintained to support high speeds over long distances as part of an interconnected motorway network


As the top non-motorway classification, highway=trunk should be applied in the following cases:

  • In areas of high population density, to expressways that meet most, but not all, of the requirements for highway=motorway, and provide connectivity between motorways and other trunk roads. These roads should also be tagged expressway=yes.
  • In areas of medium to low population density, to the most important non-motorway roads that provide principal, long-haul connections between population centers of regional importance.


Motorway and Trunks

  1. The first motorway segment listed on US 54 (part of the Cannonball Stageline) has been flipped back and forth a few times. Discussion was had on #local_kansas Slack and it was concluded that this should be motorway despite only one interchange due to the length and separation of roads through bridges or closed intersections.
