Delay and closure times are estimates only and subject to change depending on the pace of the race, weather and other unanticipated conditions.

"It's not just our electronic resources but it's also our traffic, maintenance and communication personnel that are doing what's necessary to make sure the Colorado Classic is as safe and successful as possible for riders, spectators and support personnel, while minimizing impacts to motorists," said CDOT Executive Director Michael Lewis. "Bicycling is an important part of the state's outdoor recreational economy and CDOT is proud to do its part to enhance all of the various aspects of cycling in Colorado."
