List of state highways in Colorado
The system of State highways in Colorado is a system of public paved roads funded and maintained by the Colorado Department of Transportation in the U.S. state of Colorado. These comprise state highways, U.S. Routes, and Interstate Highways. The numbered highways within the state begin at 1 and increase, with exception of numbers already designated as U.S. highways or Interstate Highways. In 1953 or 1954, many highways were decommissioned or lost mileage. Before the 1968 Colorado state highway renumbering, highways were cosigned with U.S. highways and Interstate Highways, and there were highways matching U.S. Highway and Interstate Highway numbers.List
