The 20-year, $2.1 billion Regional Transportation Authority plan was approved by Pima County voters on May 16, 2006, and is effective through June 30, 2026. To date, the RTA has invested more than $1 billion in transportation improvements across the region. More than 800 transportation improvements have been completed to date.

What is the RTA?

The Regional Transportation Authority is the fiscal manager of the $2.1 billion, 20-year RTA plan, which was approved by Pima County voters on May 16, 2006. Voters also approved a countywide half-cent transaction privilege (sales) tax to fund the RTA plan through fiscal year 2026. Both measures passed on a 3-2 margin.

The RTA is managed by Pima Association of Governments (PAG), the region's metropolitan planning organization. The RTA is the fiscal manager of the plan and projects in the plan are managed by PAG's member jurisdictions. 

The plan includes roadway, transit, safety, environmental and economic vitality improvements. Plan goals include improving safety, cross-town mobility and reducing congestion. The RTA has completed nearly 785 projects through July 2017

RTA History

The RTA was formed in 2004 after legislation creating the authority was signed by then-Gov. Janet Napolitano in April and the RTA became effective Aug. 25, 2004. As part of an extensive public involvement process, a diverse 35-member citizens committee and a 22-member technical committee developed the RTA plan in 2005 for voter approval in May 2006.

The RTA is governed by a nine-member board, which meets monthly. A Citizens Accountability for Regional Transportation (CART) Committee, established by the board, meets as needed to provide oversight on the implementation of the plan. A Technical Management Committee also meets to manage technical issues that may arise. Both committees report to the RTA Board.

RTA State Statute

State statute provides that the Regional Transportation Authority is a public body and all meetings are open to the public. Under the RTA statute, none of the RTA members has veto power which helps to foster regional collaboration.

RTA Sales Tax

The RTA plan is funded by a countywide transaction privilege tax, or sales tax, which is collected by the State of Arizona. The state, in turn, transfers the collected funds to a regional transportation fund account. The tax may be collected for a maximum period of 20 years as spelled out in the ballot. The tax applies to visitors as well as residents of Pima County.

Sales Tax Collections

The RTA transaction privilege (sales) tax* is assessed in six major categories:

  • Retail Sales
  • Contracting
  • Utilities
  • Restaurant & Bar
  • Rental of Real Property
  • Rental of Personal Property

*Grocery and pharmaceutical items are tax-exempt.
