Coming in January, 2016 - FLEX to Boulder. We are excited to announce new transit service between Fort Collins and Boulder! Enjoy a one seat ride from Fort Collins to Boulder, offering express service with limited stops. Stops on the route may include:

  • Fort Collins - South Transit Center, and possibly CSU and Downtown
  • Loveland - 8th Street

  • Boulder - Boulder Junction, Downtown Boulder, and CU

Five trips each weekday are planned; two in the morning and three in the afternoon/early evening. The trip is expected to take approximately 1 hour 15 minutes. Free WiFi will be provided.

Fares for the extended FLEX will be the same as the rest of the Transfort system (all valid passes accepted, $1.25 single ride adult fare), and RTD Ecopasses will be accepted.
