Missouri Highway Types

Missouri has two types of state highways: primary (numbered) and supplementary (lettered). The table below shows the minimum classification for state highways. These are only minimums and may need to be upgraded based on the Functional Classification or the qualities defined on the USA road type Wiki page.

 Minor Highway 
 Primary Street 


State Highway Naming

Missouri primary numbered highways are named as MO-### (e.g. MO-13, MO-7 N). This includes their related business, loops, and spurs. (e.g. MO-13 BUS)

Missouri secondary lettered highways are named as State Hwy xxx. (e.g. State Hwy F)

County Road Naming

County roads with the name designation of "County Road ###" are named as CR-### (e.g. CR-110). This shortened version takes up less space on the map screen and is announced correctly as "County Road ###" while navigating with the Waze app.

Functional Classifications

Missouri follows the Functional Classification (FC) system for the USA. Base minimum road types in the Waze editor according to the MoDOT Highway Functional Classification Maps along with guidance from the USA road type guidelines.

The table below shows a cross reference for the minimum road types in Missouri. Keep in mind that these are only minimums, and may need to be upgraded based on the qualities defined on the USA road type guidelines.


MODOT Classification Waze Road Type
  Interstate    Freeway 
  Expressway    Major Highway 
  Principal Arterial    Major Highway 
  Minor Arterial    Minor Highway 
  Urban Collector    Primary Street 
  Rural Major Collector    Primary Street 
  Rural Minor Collector    Primary Street 
  Local Road    Street 


Lock Levels

In Missouri we have a set minimum standard for locking roads based on segment type. Any road of a certain segment type must be locked at least to the rank (level) in the chart below. Roads may be locked higher for protection and special situations (areas with construction, tricky design, frequent mistakes, imaging inaccuracies, and the like), but should not be locked lower.

A great time to implement these locks is while bringing the road types of an area into compliance with the current US road type standards (FC and highway systems). Lock the roads based on type after they've been set to current US road type standards.
