Colorado GIS Links

For some of the lesser traveled or more rural areas, there may still be many errors, or even completely unedited areas. The various County Assessor’s have parcel maps that are usually up-to-date on a weekly basis for dealing with new construction that isn’t visible on aerials as well as house numbers and road names.

Functional Classification

Colorado is following the Functional Classification (FC) system for the USA.

Colorado to Waze FC conversion

Colorado’s Dept of Transportation has made an interactive statewide Functional Classification map available online.

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.

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.

Closures

The Colorado Department of Transportation keeps a running list of construction projects in the state. Note that this does not show lower level projects completed by city or county agencies.

Roads

U-turns

U-turns are generally permitted in Colorado except where prohibited by posted No U-Turn signage. Left turn only signage does not prohibit U-Turns. Here is the relevant CO Revised Statute.

C.R.S. 42-4-902. Limitations on turning around

  1. No vehicle shall be turned so as to proceed in the opposite direction upon any curve or upon the approach to or near the crest of a grade where such vehicle cannot be seen by the driver of any other vehicle approaching from either direction within such distance as is necessary to avoid interfering with or endangering approaching traffic.
  2. The driver of any vehicle shall not turn such vehicle at an intersection or any other location so as to proceed in the opposite direction unless such movement can be made in safety and without interfering with or endangering other traffic.
  3. Local and state authorities, within their respective jurisdictions, subject to the provisions of section 43-2-135 (1)(g), C.R.S., in the case of streets which are state highways, may erect “U-turn” prohibition or restriction signs at intersections or other locations where such movements are deemed to be hazardous, and, whenever official signs are so erected, no driver of a vehicle shall disobey the instructions thereof.

Special Roads for Colorado

See this Forest Service Roads section about Forest Service roads for some clarification.
