UPCOMING ROUTE CHANGES

Route 3, 11, 37, and 50 will have changes beginning February 23, 2025.
Route 3 & 37

Route 37 will serve Stella Road between Pantano Road and Camino Seco instead of Route 3. Camino Seco from Stella Road and Irvington Road will now be served by Route 37. All service on Escalante Road has been discontinued.

Route 11 & 50

Route 11 and Route 50 will merge and no longer travel on South 6th Avenue between Ajo Way and Laos Transit Center. Route 11 will now extend west on Ajo Way to Mission Road, discontinuing Route 50.


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.
