The Colorado Department of Transportation publishes an Airport Directory every other year. This directory is a valuable resource for both pilots and passengers. The directory lists each airport in the state, along with key facts about the airport. You can find out what kinds of planes are allowed at each airport, for example, and other key facts. People traveling around the state can find out if they have another option besides driving. And statistical data is presented, as well. Current and past editions of the Colorado Airport Directory may be checked out from our library; the current edition can also be accessed online.
