Treasure Valley High Capacity Transit Study

The Treasure Valley High Capacity Transit Study began in 2007 in conjunction with Valley Regional Transit and other member agencies. The study focused on connections between three related planning projects: the downtown Boise Multimodal Center, the Downtown Boise circulator, and a regional, east-west high-capacity corridor.

  • Main Street Station - Main Street Station in downtown Boise serves as a "hub" for various transportation services. The station provides multimodal connections, includes public transportation information, bicycle parking, a Boise Police Department substation, public art, restrooms, and retail space. Main Street Station is a subterraneous facility near the intersection of Main Street and Capitol Boulevard. Learn more about Main Street Station here.
  • Downtown Boise Circulator - A circulator is a form of public transportation that connects primary destinations within and adjacent to a specific area. The City of Boise is conducting a study to evaluate potential routes, types of vehicles, and costs for a circulator in the downtown Boise area. Visit for more information.
  • Treasure Valley High Capacity Corridor - A high-capacity, fixed guideway transit service to connect Caldwell to Boise, and communities in between, has been identified as a future need for the valley.

    A Rail Corridor Evaluation Study was completed in 2003 for ValleyRide in cooperation with Ada and Canyon Counties, the Ada County Highway District, the cities of Boise, Meridian, Nampa and Caldwell, COMPASS, and the Idaho Transportation Department to provide information and background necessary for an informed decision regarding a public acquisition of certain rail corridors within Ada and Canyon Counties.

    Rail Corridor Evaluation Study Volume 1 Study Report (April 2003)

    A study to begin analysis of potential corridors (e.g., “paths” or “alignments”) and potential modes (e.g., types of vehicles) was initiated in 2009 to narrow down options to move forward for a more in-depth study. Results of this study and related documents are linked below.

The recommendations contained in these reports are subject to review by the COMPASS Board.

Communities in Motion 2040 prioritized a Treasure Valley high capacity transit corridor study to further identify route alignments and modal options for the corridor. This project was listed as the 12th highest priority among 33 unfunded projects in Communities in Motion 2040 . The next step in preparing for the high capacity transit corridor is to study the “preferred alternative,” or the mode of transportation and route alignment that should be preserved for future improvements. Preservation is dependent on local government, transportation agencies, railroads, and owners of adjacent properties incorporating right-of-way needs in their future land development policies, long-range plans, and/or building approval processes. Funding is not available at this time to complete the project development and NEPA analysis to satisfy the Federal Transit Administrative requirements for a fixed guideway project.
