Colorado is a state in the western United States encompassing most of the southern Rocky Mountains as well as the northeastern portion of the Colorado Plateau and the western edge of the Great Plains. It is the 8th most extensive and 21st most populous U.S. state. The estimated population of Colorado is 5,758,736 as of 2019, an increase of 14.5% since the 2010 United States Census.
The Denver & Rio Grande Western Railroad, often shortened to Rio Grande, D&RG or D&RGW, formerly the Denver & Rio Grande Railroad, was an American Class I railroad company. The railroad started as a 3 ft narrow-gauge line running south from Denver, Colorado, in 1870. It served mainly as a transcontinental bridge line between Denver, and Salt Lake City, Utah. The Rio Grande was also a major origin of coal and mineral traffic.
Interstate 25 (I-25) is a major Interstate Highway in the western United States. It is primarily a north–south highway, serving as the main route through New Mexico, Colorado, and Wyoming. I-25 stretches from Interstate 10 at Las Cruces, New Mexico, to Interstate 90 in Buffalo, Wyoming. It passes through or near Albuquerque, New Mexico; Colorado Springs, Colorado; Denver, Colorado; and Cheyenne, Wyoming. The I-25 corridor is mainly rural, especially in Wyoming, excluding the Albuquerque, Pueblo, Colorado Springs, and Denver metropolitan areas.
Interstate 70 (I-70) is a major east–west Interstate Highway in the United States that runs from I-15 near Cove Fort, Utah, to a Park and Ride lot just east of I-695 in Baltimore, Maryland. I-70 approximately traces the path of U.S. Route 40 east of the Rocky Mountains. West of the Rockies, the route of I-70 was derived from multiple sources. The Interstate runs through or near many major cities, including Denver, Topeka, Kansas City, St. Louis, Indianapolis, Columbus, Pittsburgh, and Baltimore. The sections of the interstate in Missouri and Kansas have laid claim to be the first interstate in the United States. The Federal Highway Administration has claimed the section of I-70 through Glenwood Canyon, Colorado, completed in 1992, was the last piece of the Interstate Highway system, as originally planned, to open to traffic. The construction of I-70 in Colorado and Utah is considered an engineering marvel, as the route passes through the Eisenhower Tunnel, Glenwood Canyon, and the San Rafael Swell. The Eisenhower Tunnel is the highest point along the Interstate Highway system, with an elevation of 11,158 ft (3,401 m).
U.S. Route 34 (US 34) is an east–west United States highway that runs for 1,122 miles (1,806 km) from north-central Colorado to the western suburbs of Chicago. Through Rocky Mountain National Park it is known as the Trail Ridge Road where it reaches elevation 12,183 feet (3,713 m), making it the third highest paved through highway in the United States. The highway's western terminus is Granby, Colorado at US 40. Its eastern terminus is in Berwyn, Illinois at Illinois Route 43 and Historic US 66.
Interstate 76 (I-76) is an Interstate Highway in the Western United States that runs from Interstate 70 in Arvada, Colorado to an intersection with Interstate 80 near Big Springs, Nebraska. All but three miles of the highway's route is in Colorado.
State Highway 82 is an 85.3-mile-long (137.3 km) state highway in the U.S. state of Colorado. Its western half provides the principal transportation artery of the Roaring Fork Valley on the Colorado Western Slope, beginning at Interstate 70 (I-70) and U.S. Highway 6 in Glenwood Springs southeast past Carbondale, Basalt and Aspen. From there it continues up the valley to cross the Continental Divide at Independence Pass. On the Eastern Slope, it follows Lake Creek past some of Colorado's highest mountains to Twin Lakes Reservoir, where it ends at US 24 south of Leadville.
The San Juan Skyway is an All-American Road and a component in the Colorado Scenic and Historic Byway System. It forms a 233.0-mile (375.0 km) loop in the southwest part of the U.S. state of Colorado traversing the heart of the San Juan Mountains. It roughly parallels the routes of the narrow gauge railways: Rio Grande Southern ; and the unconnected Ouray and Silverton Branches of the Denver & Rio Grande along US 550 with the Silverton Railroad bridging a part of the gap. Its origin can be traced to the Around the Circle Route promoted by the D&RG.
Interstate 70 (I-70) is a mainline route of the Interstate Highway System in the United States connecting Utah and Maryland. The Utah section runs east–west for approximately 232 miles (373 km) across the central part of the state. Richfield is the largest Utah city served by the freeway, which does not serve or connect any urban areas in the state. The freeway was built as part of a system of highways connecting Los Angeles and the northeastern United States. I-70 was the second attempt to connect southern California to the east coast of the United States via central Utah, the first being a failed attempt to construct a transcontinental railroad. Parts of that effort were re-used in the laying out of the route of I-70.
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.
U.S. Route 50 (US 50) is a part of the U.S. Highway System that travels from West Sacramento, California, to Ocean City, Maryland. In the U.S. state of Colorado, US 50 is a major highway crossing through the lower midsection of the state. It connects the Western Slope with the lower Front Range and the Arkansas Valley. The highway serves the areas of Pueblo and Grand Junction as well as many other smaller areas along its corridor. The long-term project to upgrade the highway from two lanes to a four lane expressway between Grand Junction and Montrose was completed in January 2005. Only about 25% of the remainder of highway 50 in Colorado is four lane expressway.
The original Maroon Creek Bridge is a steel trestle along State Highway 82 at the western boundary of Aspen, Colorado, United States. It was designed by George S. Morison in 1888 for the Colorado Midland Railroad, one of the last viaducts in Colorado built for a standard gauge mountain railroad in the 19th century. Of the five steel bridges the Midland built, it is the only one still extant. Due to the later removal of most track and the rail depots, the bridge is the most visible remnant of rail service to Aspen. In 1985 it was listed on the National Register of Historic Places along with other highway bridges in the state, including the Sheely Bridge, also in Aspen.
In the U.S. 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, Loveland, and Pueblo. The route is concurrent with U.S. Highway 87 through the entire length of the state. I-25 replaced U.S. Highway 87 and most of U.S. Highway 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.

The following outline is provided as an overview of and topical guide to the U.S. state of Colorado:
State Highway 74 (SH 74) is a state highway in the U.S. state of Colorado. Running 18 miles (29 km) from Interstate 70 (I-70) in El Rancho to SH 8 in Morrison, the highway roughly follows a hook-shaped path running northwest–southeast. The section of the route north of the town of Evergreen is known as Evergreen Parkway and is a segment with a four- to six-lane roadway, with the section east of Evergreen mostly two lanes. The other section is known as the Bear Creek Canyon Scenic Mountain Drive, or just Bear Creek Road, and primarily parallels Bear Creek, passing through the towns of Kittredge and Idledale. The route, which is on the outskirts of Denver, passes through several of the city's mountain parks, including Bergen, Dedisse and Red Rocks parks.
The Alamosa–Durango line or San Juan extension was a railroad line built by the Denver and Rio Grande Western Railroad, following the border between the U.S. states of Colorado and New Mexico, in the Rocky Mountains. The line was originally built as a 3 ft narrow-gauge line between Alamosa, Colorado, and Durango, Colorado. Portions of the route survive to this day: the now standard-gauged segment from Alamosa to Antonito, Colorado, and a narrow-gauge portion from Antonito to Chama, New Mexico.
Bustang is an intercity bus service in the U.S. state of Colorado. Service began in 2015 and originally traveled between Denver and Colorado Springs, Fort Collins, and Glenwood Springs. Service has since been expanded to connect Grand Junction, Durango, Gunnison, Alamosa, Pueblo, and Lamar among others. It is Colorado's first state-run bus service.
