RTD Staff

DENVER (April 28, 2025) –– The Regional Transportation District (RTD) is hosting a public informational webinar in early May and online public survey throughout May and June regarding future Bus Rapid Transit (BRT) service between Boulder and Longmont.

The webinar will offer details about proposed stations, stops, frequencies and service levels for the two Diagonal Flyer routes (DF1 and DF2) that will operate along the CO 119 corridor, also known as the Diagonal, when the BRT begins operating service in 2027.

Participants can access the Zoom meeting link on the Community Events page of the RTD website. Three time slots are offered for the online webinar:

  • Monday, May 5, noon-1 p.m.
  • Monday, May 5, 5:30-6:30 p.m.
  • Tuesday, May 6, 5:30-6:30 p.m.

The webinar is an informational meeting with no public comment scheduled during the session. Customers are invited to share feedback on the proposed DF1 and DF2 routes through a service hours and frequency online survey that will be offered during May and June on the CO 119 Bus Rapid Transit Project webpage.

Additional feedback opportunities will be available during service change public meetings that will take place in February 2027 ahead of the proposed May 2027 start of service for the Diagonal Flyer routes. RTD adjusts its schedule three times a year, generally in winter, spring and fall, to address ridership changes, traffic patterns, maintenance activities and customer feedback that affect its bus and rail service.

About the proposed CO 119 Bus Rapid Transit (BRT) Diagonal Flyer Service

The CO 119 BRT project will optimize regional connectivity and mobility between Boulder and Longmont by providing improvements that result in faster, safer and more reliable transit travel.

RTD is partnering with the Colorado Department of Transportation (CDOT) and Boulder County to integrate the CO 119 Bus Rapid Transit project with other active multimodal projects on the corridor to ensure community members can safely and reliably travel throughout the corridor using their mode(s) of choice.
