The Colorado Department of Transportation (CDOT, pronounced See Dot) is the principal department of the Colorado state government [2] that administers state government transportation responsibilities in the state of Colorado. CDOT is responsible for maintaining 9,144 mile highway system, including 3,429 bridges with over 28 billion vehicle miles of travel per year. CDOT's Mission is "To provide the best multi-modal transportation system for Colorado that most effectively moves people, goods, and information." [3] It is governed by the Transportation Commission of Colorado. [4]
Motor Carriers over 10,000 lbs are regulated by the state and are required to obtain a federal United States Department of Transportation (USDOT) safety tracking number used to monitor carriers' safety management practices and controls.
The Colorado Department of Transportation has its roots in 1909, when the first highway bill was passed by forming a three-member Highway Commission to approve work and allocate funds. The Commission first took their post on January 1, 1910. In 1917 the State Highway Fund was created and the State Highway Department was formed. In 1935, Highway Department employees were joined by 44 new co-workers selected from among 7,500 applicants to become the first members of the Colorado State Highway Courtesy Patrol. The Patrol became a division of the Highway Department.
In 1947, the first National System of Interstate and Defense Highways was approved by the federal works administrator. In Colorado, approved routes included all of I-25 from the Wyoming border to Raton Pass; all of I-80S (now I-76); and I-70 from Denver to the Kansas border. In 1953 the state legislature passed a new law reorganizing the Highway Department and renaming it the Colorado Department of Highways. In 1956, Congress passed the Federal Interstate Highways Act. Among the approvals was the section of I-70 from Denver to the Utah border. In 1968, legislation reorganized highway matters and created the Colorado Department of Highways (CDOH) with 3 main divisions: Division of Highways, Division of Planning and Research, and Division of Patrol. In 1991 – CDOH became CDOT to better align its functions and budgets with Federal Highway Administration / U.S. Department of Transportation.
The state adopted a low emission vehicle standard in 2018 and a Zero emission vehicle standard in 2019, which are projected cause a reduction in greenhouse gas emissions of 6 million tons of carbon dioxide equivalent by 2030. [6] This is part of Governor Jared Polis's plan to cut transportation emissions by 40% below 2005 levels by 2030. [7]
In 2019, Shoshana Lew assumed leadership of CDOT. [8] Under her leadership, the Colorado Transportation Commission approved a policy designed to stop any increases in greenhouse gas emissions from transportation in Colorado, by requiring transportation planners to calculate any emissions associated with a project and mitigate accordingly. [9] The policy was approved by the State Transportation Commission on a 10-1 vote. [10] Apart from environmental benefits, this policy could deliver $40 billion in economic benefits, including fewer traffic collisions. [11]
Under this policy, the governor-appointed Colorado Transportation Commission would have authority to restrict funding for use only on climate-friendly transportation projects if the CDOT or a regional planning authority fails to meet its emissions reduction target. Lew stated that this policy allows for capacity increases, but that major projects would require offsets in the form of climate-friendly additions. Examples include the Bustang and Flatiron Flyer bus systems that serve Colorado communities. [9] The transportation commission would also have the authority to grant waivers to this policy. Lew stated this policy enables Colorado to "lead by example" in reducing emissions, in the face of increasing impacts of climate change. [10] [12] The policy has received nationwide plaudits for "showing us how to end America's addiction to highway expansion". [13] However, it also received criticism for some who were concerned that the CDOT had become "preoccupied with cleaning the air." [9]
CDOT maintains the state highways in Colorado. The main arteries include Interstate 25, Interstate 70, and Interstate 76. It takes information from the Colorado Avalanche Information Center to ensure safety in winter months.
The Colorado Department of Transportation operates the Bustang as an intercity bus service to connect the regions of Colorado to each other. [14] It also provides support for other bus systems in the state, such as the Flatiron Flyer which connects Boulder, Colorado to Denver, which is directly operated by the Regional Transportation District.
The Colorado Division of Aeronautics is a part of the CDOT. It was created by statute in 1988 and is responsible for the development of aviation in Colorado. [15]
Long-distance intercity passenger rail service in Colorado is provided by Amtrak on the California Zephyr and Southwest Chief, which operate long-distance cross-country routes on east-west alignments, through central and southern Colorado respectively.
Light rail and commuter rail service in the Denver metropolitan area is provided by the Regional Transportation District, which also operates local and regional bus service. The bus and rail service is known as RTD Bus & Rail, and provides a comprehensive system of transit for that region.
There have been persistent proposals for a Front Range Passenger Rail system, but they have not been implemented as of yet. This means that there is no rail service connecting the state's major population centers.
In addition, the following Heritage railways operate within Colorado.
The vast majority of passenger travel in the United States occurs by automobile for shorter distances and airplane or railroad for longer distances. Most cargo in the U.S. is transported by, in descending order, railroad, truck, pipeline, or boat; air shipping is typically used only for perishables and premium express shipments. Transportation is the largest source of greenhouse gas emissions in the United States.

Interstate 76 (I-76) is an east–west Interstate Highway in the Western United States that runs from I-70 in Arvada, Colorado – near Denver – to an interchange with I-80 near Big Springs, Nebraska. The highway measures 187.29 miles (301.41 km) long, mostly situated in Colorado but approximately three miles (4.8 km) of which is in Nebraska. Along the route, the highway runs concurrent with US 6, US 85 in the Denver metropolitan area, and US 34 from Wiggins to Fort Morgan. It has no auxiliary Interstates, but it has two business routes that are located in northeastern Colorado. This route is not connected with the other I-76 that spans from Ohio to New Jersey.
Interstate 225 (I-225) is an auxiliary Interstate Highway in the U.S. state of Colorado. The freeway is a 11.959-mile-long (19.246 km) connector spur route of I-25 that acts as an eastern bypass in the Denver metropolitan area and serves Aurora. It also provides direct access to Denver International Airport for the Denver Tech Center and the southern suburbs of Denver. I-225 is one of the two existing auxiliary Interstate Highways in Colorado and it is the only auxiliary route of I-25. The route begins at I-25 in the Denver Tech Center and runs north to I-70 north of Aurora. It interchanges with State Highway 83 (SH 83), SH 30 and I-70 Business/US 40/US 287, known locally as Colfax Avenue. The freeway was first proposed in the 1950s along with the first Interstate Highways within Denver. Construction did not begin until 1964 at the I-70 interchange and proceeded south through Aurora until final completion in early 1976 with the final link to I-25 opening to traffic.
Front Range Passenger Rail is a proposed intercity passenger train service along the Front Range and broader I-25 corridors in Colorado and Wyoming. Most proposals envision a route from Pueblo north to Colorado Springs, Denver, Boulder, and Fort Collins. Extensions north to Cheyenne and south to Trinidad, Albuquerque, and even El Paso have been discussed.
Front Range Express was a commuter bus service that began in 2004 and operated between the cities of Colorado Springs and Denver, with stops along the way in Greenwood Village, Monument and Castle Rock in Colorado, USA. FREX operated on Interstate 25 except when exiting to make stops at each city. FREX served the southern portion of the Colorado Front Range and during its tenure was operated via different contracts by Veolia Transport & Laidlaw Transit. It was added as a part of Mountain Metropolitan Transit, which serves the Colorado Springs and El Paso County areas. In 2005, annual ridership was 118,389 and daily ridership was 464.
California's transportation system is complex and dynamic. Although known for its car culture and extensive network of freeways and roads, the state also has a vast array of rail, sea, and air transport. Several subway, light rail, and commuter rail networks are found in many of the state's largest population centers. In addition, with the state's location on the West Coast of the United States, several important ports in California handle freight shipments from the Pacific Rim and beyond. A number of airports are also spread out across the state, ranging from small general aviation airports to large international hubs like Los Angeles International Airport and San Francisco International Airport.
Interstate 70 (I-70) is a transcontinental Interstate Highway in the United States, stretching from Cove Fort, Utah, to Baltimore, Maryland. In Colorado, the highway traverses an east–west route across the center of the state. In western Colorado, the highway connects the metropolitan areas of Grand Junction and Denver via a route through the Rocky Mountains. In eastern Colorado, the highway crosses the Great Plains, connecting Denver with metropolitan areas in Kansas and Missouri. Bicycles and other non-motorized vehicles, normally prohibited on Interstate Highways, are allowed on those stretches of I-70 in the Rockies where no other through route exists.
The Transportation Expansion (T-REX) Project was a $1.67 billion project aimed at improving transportation options for commuters in the Denver metro area within the areas of Interstate 25 and 225, which was recognized as the 14th busiest intersection in the United States at the time. The T-REX effort widened major interstates to up to 5 mainline lanes in each direction and added 19 miles (31 km) of double-track light rail throughout the metropolitan area. The T-REX project finished 3.2% under its $1.67 billion budget and 22 months ahead of schedule in 2006.
In the US state of Colorado, Interstate 25 (I-25) follows the north–south corridor through Colorado Springs and Denver. The highway enters the state from the north near Carr and exits the state near Starkville. The highway also runs through the cities of Fort Collins, Broomfield, Loveland, and Pueblo. The route is concurrent with U.S. Route 87 (US 87), which is unsigned, through the entire length of the state. I-25 replaced US 87 and most of US 85 for through traffic.
Colorado's transportation consists of a network of highway, surface street, rail, and air options. While the public transportation system in Denver is much more complex and developed than other parts of the state, tourism and growth have led to extensive needs statewide.
Lakewood is the home rule municipality that is the most populous municipality in Jefferson County, Colorado, United States.
