  • Route 25 Detour

    Due to a road closure on southbound Park Avenue near Interstate 10, Route 25 is on a temporary detour until further notice. While all bus stops will still be serviced, passengers may experience short delays due to the detour. Note: the real-time bus tracking feature on the Sun Tran app will not display the bus position while it is on the detoured section of the route. Tracking will resume once the bus rejoins the regular route area.
