The Regional Transportation Authority is a state-established political subdivision within Pima County, Arizona, since 2004 and is the fiscal manager of the RTA’s 20-year voter-approved regional transportation plan. Pima County voters approved the original RTA plan in 2006 and a new 20-year plan in March 2026. The plan is funded by a half-cent transaction privilege or sales tax, also approved by voters in 2026. Tax collections on the new RTA plan began April 1, 2026, and will continue through March 31, 2046.
The RTA, which is managed by Pima Association of Governments through a memorandum of understanding, is the fiscal manager of the tax revenues and oversees plan delivery of roadway, transit, bicycle, pedestrian, signal technology and other transportation network improvements across the greater Tucson region. Improvement projects are managed by the RTA and RTA members, which include local, county, state and tribal governments. More than 1,050 transportation project and service improvements have been delivered to date.
Local, county, state and tribal leaders, who serve on the RTA Board as well as the PAG Regional Council, are working together to improve the region’s livability by delivering a quality transportation network for all users.
