The City of Tucson and Sun Tran, in partnership with the Pima Association of Governments (PAG), evaluated all aspects of Sun Tran, Sun Link, Sun Express, and Sun Shuttle services throughout Tucson, and the greater Tucson area to determine potential improvements through the COA.

Following nearly 11 months of public outreach to gather input on proposed changes to improve transit efficiency, equity, and effectiveness, Sun Tran staff will host six (6) public meetings to discuss the Comprehensive Operational Analysis (COA) proposed transit changes. The meetings will begin Monday, January 22 through Monday, January 29.

Join us at one of our upcoming events below to learn more about the proposed changes.
