Cheyenne is the state capital and largest city (2005 pop. 55,731) of Wyoming. Cheyenne was founded in 1867 by Major General Grenville Dodge, the chief engineer of the Union Pacific Railroad. In 1869, Cheyenne became the capital of the Territory of Wyoming. It became the state capital in 1890.
Cheyenne is located at the crossroads of Interstate-80 and Interstate-25 in southeastern Wyoming.
Cheyenne is 40 miles east of the Nebraska border and 8 miles from the Colorado border. Cheyenne is 90 miles directly north of Denver. The trip takes approximately 1 ½ hours, depending on Denver traffic. Cheyenne has no traffic problems.
The closest major airport is Denver International Airport (IATA: DEN). Rental cars are available at DEN. Shamrock Airport Express has shuttles from DEN to Cheyenne with drop-offs at the Holiday Inn and the Best Western Hitching Post, via the Harmony Transfer Center in Fort Collins, Colorado.
For the adventurous, small 15-seat prop planes fly from DEN to the Cheyenne Regional Airport (IATA: CYS). The flight is not recommended for those with weak stomachs or those who hate roller coaster rides. Great Lakes Airlines operates the 40 minute flights (about 20 minutes of actual flying time) and code shares with Frontier and United.
Cheyenne is pretty much an automobile- and bike-friendly city. There is, however, also a public bus service.
