Denver International Airport

Since opening on Feb. 28, 1995, Denver International Airport (DEN) has become the world’s 17th- busiest airport and the fifth-busiest airport in the United States. With nearly 53 million passengers in 2011, DEN is one of the busiest hubs in the world’s largest aviation market, the United States, and is Colorado’s primary economic engine, generating more than $26 billion in annual economic impact for the state (Colorado Department of Transportation, 2013). DEN is one of the few major U.S. airports with room to expand its current facilities to accommodate future growth. Encompassing 53 square miles (137.8 square kilometers) of land, DEN is twice the size of Manhattan Island, and is larger than the city boundaries of Boston, Miami, or San Francisco. DEN is the largest airport site in North America and the second-largest in the world. The efficient layout of six non-intersecting runways allows for multiple simultaneous aircraft movements.
