As Sun Tran officials and representatives of Teamsters Local 104 continue to negotiate a new contract, the current contract extension is set to expire at 11:59 tonight. In the event of a work stoppage, Sun Tran will offer limited weekday service from approximately 6 a.m. to 6 p.m. on Routes 3, 8, 11, 16, and 18. Service maps and schedules are available at transit centers and the Sun Tran website. You also can call (520) 792-9222 and monitor social media. If a strike is called it would apply only to buses, not the Sun Link streetcar and other services.
