Construction of Pima County’s Sunset Road, Silverbell Road to Interstate 10, improvement project is complete. This is also a project in the Regional Transportation Authority plan which was approved by voters in 2006. For information go to and click on Current & Future Roadway Projects.

The Regional Transportation Authority, a political subdivision of the state and independently governed, has invested more than $1.2 billion in transportation projects and services to improve mobility, safety, economic vitality and quality of life in the region. The RTA collects a half-cent excise (sales) tax from its special taxing district within Pima County to fund its 20-year regional transportation plan. The plan and tax were approved by voters in May 2006. 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.
