Welcome to Arapahoe County, Colorado the state's first county and one of the largest with a population of more than 500,000. Arapahoe County was named for the Arapaho Indians, who along with the Cheyenne Indians, occupied most of Colorado when it was only a territory.
Back then, Arapahoe County was much larger stretching east to western Kansas. Denver was the original County seat until 1902 when the city split off and became a separate county. The City of Littleton became the new county seat and remains the county seat today. The County Administration Building is located at 5334 S. Prince Street in Littleton, Colorado.
South Metro commuters now have an alternative to using the Parker and Arapahoe roads intersection with the new Broncos Parkway Bridge in Centennial. Construction of Broncos Parkway Bridge, which spans the Cherry Creek, began in June 2003 and opened on schedule, approximately $30,000 under budget. An estimated 8,000 to 10,000 vehicles a day are expected to use the bridge with a projected 20,000 to 25,000 vehicles per day in future years.
