Pinal Regional Transportation Authority

What is the PRTA?

The Pinal County Board of Supervisors established the Pinal Regional Transportation Authority (PRTA) in 2015 as a public improvement and taxing subdivision of the State of Arizona to coordinate multi-jurisdictional transportation planning, improvements, and funding. This is an entity authorized and defined in Arizona Revised Statutes Title 48 (Special Taxing Districts), Chapter 30 (Regional Transportation Authority). The PRTA is comprised of members from Pinal County plus municipalities and tribal nations within the county.

This organization developed a Regional Transportation Plan (RTP) that was taken to the voters in a November 2017 Special Election. The voters of Pinal County approved both the RTP and a 20-year half-cent sales tax to fund the transportation improvements contained in the plan. However, the structure of the tax was challenged in a 2018 lawsuit and ruled invalid by the Arizona Supreme Court in March 2022, so implementation of the Plan has not yet begun.

Proposition 469 on the November 8, 2022 General Election ballot will offer Pinal County voters a second chance to fund Plan implementation through a restructured half cent sales tax that is projected to generate nearly $1.1 billion between the years 2023 and 2043. Voter approval of this proposition would allow plan implementation to begin around July 1, 2023, the start of the 2024 fiscal year.

Proposition 469 not approved by Pinal County Voters – Regional Transportation Plan lacks funding

On November 8, 2022, Pinal County’s voters turned down Proposition 469, which would have generated an estimated $1.1 billion for transportation projects and programs in the county between 2023 and 2043. Election results are not completely finalized, but the proposition appears to have been rejected by a narrow margin.

With this result, no revenue source exists to fund the voter-approved 2017 Pinal County Regional Transportation Plan, including a countywide program of roadway and public transportation improvements. This plan was developed by the Pinal Regional Transportation Authority (PRTA), created by Pinal County in 2015.

Rapid population and employment growth continue in Pinal County, contributing to increased traffic congestion. It is anticipated that these issues will need to be revisited as traffic conditions worsen.
