Denver, CO

Denver, Colorado

The City of Denver is the capital of Colorado and has the highest population in the state. The city is named after James W. Denver, who was Governor in 1858 of the Territory of Kansas, which extended from Missouri to the Rocky Mountains. The State of Colorado was part of the Kansas territory at that time. The Denver-Aurora-Lakewood MSA includes 10 counties.  The Denver MSA includes Adams, Arapahoe, Broomfield, Clear Creek, Denver, Douglas, Elbert, Gilpin, Jefferson, and Park counties.

The Regional Transportation District (RTD) provides public transportation in eight counties including all of Boulder, Broomfield, Denver, and Jefferson counties, parts of Adams, Arapahoe and Douglas counties, and a small portion of Weld County. The RTD was created in 1969 by the Colorado General Assembly to focus on regional transportation planning. In 1973 voters approved a 0.5% sales tax initiative which has helped to finance a $1.56 billion multimodal transit system and expand routes, acquire private bus companies and improve service throughout the Denver metro area. Today, sales and use tax is RTD’s primary revenue source.
