The state highways of Colorado are a system of public paved roads funded and maintained by the Colorado Department of Transportation (CDOT) in the U.S. state of Colorado. These are state highways, which are typically abbreviated SH. The numbered highways within the state begin at 1 and increase, with exception of numbers already designated as United States Numbered Highways or Interstate Highways. In 1953, 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.
Description
The numbered state highway system covers approximately 3,135 miles of road in Colorado, subtracting the total miles of Interstate and US Highways from 9,100 miles of the state highway system.[1] These are maintained using state funds which are collected by state and federal gas tax and a portion of vehicle registration fees.[2] Unlike the numbering systems of the Interstate Highway System and the United States Numbered Highway System handled by the American Association of State Highway and Transportation Officials (AASHTO), the numbered state highway system is a separate system used by the state. The route markers used are separate from neighboring states rather than being consistent. In Colorado, the route markers are designed with the state flag on the top half and the number on the bottom half. Most state highways are generally two lane roads with speed limits up to 65 miles per hour in rural areas but can drop as low as 30 miles per hour in served communities. In urban areas, they can be six to eight lane expressways primarily in Denver and Colorado Springs. Some numbered routes are concurrent with US highways and Interstate Highways and concurrent sections of state highway are not recognized by CDOT. Concurrent sections generally has its mileage based off the Interstate or US Route mileage (e.g. SH 88 being concurrent with I-25) and are sometimes unsigned.[3] The longest state highway is State Highway 14 with a span of nearly 237 miles (381 km) between Muddy Pass and Sterling. State Highway 110 is the shortest route maintained by CDOT with a span of 0.186 miles (0.299 km). The Colorado Department of Transportation (CDOT) is the agency responsible for maintaining the Colorado State Highway System, including Interstate Highways, United States Numbered Highways, and numbered state highways within the state of Colorado.[4]
