Project Map

The Regional Transportation Authority is a state-established political subdivision within Pima County that collects a half-cent excise tax from the RTA’s special taxing district. The tax funds the RTA’s 20-year regional transportation plan, which voters in the district approved in May 2006 along with the excise tax. To date, the RTA has invested over $1 billion in the region to deliver transportation projects and services that improve our region’s mobility, safety, economic vitality and quality of life. The Silverbell Road project is part of the RTA plan and is managed by the City of Tucson in conjunction with the Town of Marana and Pima County.
