The Colorado Functional Classification system is on par with the Nationwide standard.
CO to Waze FC conversion
Colorado's Dept of Transportation has made an interactive statewide Functional Classification map available online.
- CDOT Interactive Functional Classification Map - In the CDOT Layers window, you need to click the triangle beside Base Layers, and then select HIGHWAYS: FUNCTIONAL CLASS and MAJOR ROADS.
CDOT to Waze conversion table
In order for you to use this table correctly, you need to have Major Roads turned on in the state's Interactive Map.
|Interstate||Interstate Business Loop/Spur||US Hwy (incl. some special routes)||State Hwy (incl. some special routes)||State Hwy BUS, SPUR, LOOP||Locally-maintained|
|example>>>>>||I-25 N||I-25 BUS||US-6||SR-28||SR-24 Spur||Fremont St|
- When a state highway "SPUR" route is used to connect a state highway with another state highway, a US highway, or an Interstate (i.e., when it is used as a connector/CONN route), use the first state highway column.
If you encounter a specific type of road (Interstate/US Hwy Business route, etc) that is not shown, reference the main FC Quick Reference chart
NOTE: Be careful not to confuse Major Roads with Streets since their colors are similar.
