Airport Transit CenterTesting of bus operations at the new Airport Transit Center is taking place. It opens in conjunction with the University of Colorado A Line from Denver Union Station to the airport. Testing with radios, automatic vehicle tagging and maneuverability show that the systems are all functioning properly.
Starting April 24th, the public will no longer go to Level 5, West Terminal to catch RTD buses, but will instead go to the new transit center located under the new Westin Hotel to the south of the main terminal area.
