Transportation Sales Tax

In 2001 the voters of Boulder County passed a ballot issue that allowed for a 0.1 percent (one cent on a $10 purchase) countywide transportation sales tax. In 2007, voters approved an extension of the sales tax through 2024. View information about the projects that receive funding from the current transportation sales tax, and information about the county’s proposed transportation sales tax extension.

The Transportation Sales Tax helps fund:

  • Roadway improvements

  • Priority transit programs
  • Pollution reduction
  • Congestion reduction
  • Safety
  • Efficiency of alternative modes and traffic flows
  • Road widening projects
    • Addition of shoulders appropriate for cycling where approved
