Functional Classification

Functional Classification Implementation has been partially completed within Utah. In some areas, mainly rural, it is still ongoing.

Please refer to this forum topic for more information on FC Road Types (USA) – comprehensive overhaul of drivable roads

The Utah Functional Classification system is on par with the Nationwide standard, and consists of 7 Road Types.

Utah's Dept of Transportation has made Functional Classification maps available online, in PDF format, for each county. They also provide an interactive statewide map.

UDOT GIS class and color description

The Utah Classification and Color scheme come from the official Utah D.O.T (UDOT) Functional Classification (FC) map that is published by UDOT. The legend shows what classifications UDOT uses and what color is assigned to each class.

↑ 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
