RTD, in collaboration with northwest area elected officials, business leaders, and public agencies, completed a comprehensive study that evaluated the viability of bus rapid transit (BRT) along SH 119 between Boulder and Longmont. The study recommended cost-effective mobility improvements to address the growing congestion and travel demand that includes a 2-pattern BRT route and BRT/managed lanes. The study also gauged environmental impacts, multimodal access, transit reliability, and transit travel time. See project summary.

Participating in the study were the cities of Boulder and Longmont, Boulder County, Longmont and Boulder chambers of commerce, Niwot Business Association, Commuting Solutions, Boulder Transportation Connections, North Area Transportation Alliance, Northwest Chamber Alliance, Colorado Department of Transportation, Denver Regional Council of Governments, Federal Transit Administration, Federal Highway Administration, BNSF, and the University of Colorado at Boulder.

Update: On December 17, 2019, the RTD Board of Directors accepted the Multimodal Corridor Vision Plan for the SH 119 corridor as defined in the Planning and Environmental Linkages (PEL) Study.  RTD has currently committed $30 million to the transit elements of the corridor.  CDOT and local stakeholders have also provided additional funding for the corridor.  Construction on various elements of the vision could begin in 2021. 

What is BRT?

BRT is a proven bus-based transit system that delivers fast, comfortable and reliable service along a designated corridor. The system has limited stops to improve speed, reduce travel time and maximize ridership.

Graphic explaining distinct BRT features on bus and at stations
  • BRT service has been proven nationally to provide riders with a convenient, frequent, and reliable travel option as an attractive alternative to an automobile.
  • The study advances one of the recommendations from the 2013 Northwest Area Mobility Study for a cost-effective enhanced transit investment along SH 119.
