Countywide Transportation Sales Tax: List of Projects

Countywide Transportation Sales Tax: List of Projects

The year 2018 marks the 9th year of the 15-year Countywide Transportation Sales Tax approved by voters in November 2007. The ballot issue funds a specific list of 44 projects that includes:

  • 10 roadway improvements
  • 13 road shoulder projects
  • 6 transit projects
  • 1 Transportation Demand Management (TDM) program
  • 5 pedestrian improvements
  • 9 countywide regional sales projects.

Seven Year Update

Now past the halfway point of the 15-year program, Boulder County has developed a comprehensive update of the first 7 years of the tax that lists projects completed and the projects yet to be started. The April 2017 Countywide Transportation Sales Tax Update includes:

  • An overview of the program
  • An analysis of milestones
  • Recommendations for the remainder of the program

The table below identifies current countywide Transportation Sales Tax projects planned for construction in the next three years. A full implementation schedule for all projects is available here.

Projects are listed by anticipated year of implementation based on the best available information. Ongoing transit projects are listed separately at the bottom of the table. These projects use Countywide Sales Tax to increase frequencies on existing regional routes. When available, the project name links to a project page with more information.
