Quick Answer: How to Check the Sun Tran Bus Schedule Today
For a Sun Tran bus schedule, start with the official Routes & Services page or the Transit app. If you know the route, open the Sun Tran/Sun Express route page. If you only know your destination, use the trip planner or app. Then confirm detours, holiday service, exact stop, service type and whether your trip uses Sun Tran, Sun Express, Sun Link, Sun Van, Sun On Demand or Sun Shuttle.
- Use the Transit app for nearby routes, next departure times, trip planning and GO directions.
- Use Alerts and Detours before leaving because construction and event detours can move stops.
- Use Holiday Schedules before major holidays because Sun Tran, Sun Express, Sun Link, Sun Van and Sun Shuttle can operate differently.
- Use Sun Link for streetcar trips through Mercado, Downtown, 4th Avenue, Main Gate and University of Arizona.
- Use Sun Van for ADA paratransit eligibility and reservations, not regular fixed-route planning.
- Use Sun On Demand or Sun Shuttle only when your trip fits the official service area and reservation rules.
Sun Tran says Sun Tran, Sun Link, Sun Van, Sun On Demand, Sun Express and Sun Shuttle rides continue to remain fare free at the direction of the Mayor and Council. Always re-check the official fare page before publishing fare details or riding after a policy change.

Sun Tran App: Transit App, Live Arrivals, GO Trip and Service Changes
Sun Tran identifies the Transit app as its official app. Riders can plan a trip, check bus arrival time, stay updated on service changes and use GO trips with step-by-step audio and visual directions. The app can also include Sun Link, Sun Shuttle and Sun On Demand options while planning a trip.
- Search “Transit” in your app store and set preferences to Sun Tran.
- Allow location permission for nearby routes and next departures.
- Use the search bar to enter a destination by name or address.
- Compare suggested trip options before choosing one.
- Use GO mode for stop reminders, connection help and trip instructions.
- Check service changes before leaving if the app suggests a route you do not normally use.
App tip
No account is required to track buses or plan trips in the Transit app. For the best arrival estimates, keep location permissions turned on and press GO when you want trip notifications.
Sun Tran Alerts, Detours and Holiday Schedules
Sun Tran publishes construction, event detours and route alerts on the official Alerts and Detours page. Riders can also view alerts in the trip planner by selecting the Alerts tab. This matters because a route may be operating but skip a specific stop or use a temporary stop nearby.
When to check alerts
- Before work, class, medical visits, school trips or airport connections.
- Before riding through Downtown Tucson, University of Arizona, Park Avenue, Grant, Speedway or construction-heavy corridors.
- When a bus stop is missing, covered, blocked or surrounded by construction.
- When the Transit app, trip planner and a printed schedule do not match.
- Before festival, parade, street fair, 4th Avenue, downtown, sports or university event travel.
Holiday schedule caution
Sun Tran’s official holiday page says some holidays use regular schedules while others use Sunday schedules, no Sun Express service, adjusted Sun Link hours, or limited Sun Shuttle ADA Dial-A-Ride service. Do not assume every holiday works the same way.
Sun Link Streetcar: Downtown, 4th Avenue, Main Gate and University of Arizona
Sun Link is often the best option for trips through Tucson’s core activity corridor. The streetcar connects Mercado San Agustín, Downtown Tucson, 4th Avenue, Main Gate Square and the University of Arizona. It is useful for students, downtown workers, visitors, event riders and anyone trying to avoid parking in busy areas.
Mercado
Use Sun Link for west-end Mercado and MSA Annex access.
Downtown
Use the streetcar for downtown restaurants, offices, hotels and entertainment.
4th Avenue
Use Sun Link for the 4th Avenue shopping, dining and event corridor.
University area
Use the streetcar for Main Gate Square and University of Arizona connections.
Sun Van and Sun On Demand: Reservation Rules, Eligibility and Service Differences
Sun Van and Sun On Demand are not the same as regular Sun Tran fixed-route buses. Sun Van is ADA paratransit for certified eligible riders who cannot use Sun Tran because of a disability.

Sun Van basics
- Sun Van requires ADA paratransit eligibility.
- Eligibility is not based only on age or social service needs.

Do not mix service rules
Fixed-route Sun Tran, Sun Link, Sun Van, Sun On Demand and Sun Shuttle each have different planning rules. Always read the correct official page for the service you are actually using.
Sun Shuttle: Oro Valley, Marana, Green Valley, Sahuarita, Ajo and Neighborhood Connections
Sun Shuttle is important for riders outside the core Sun Tran fixed-route network. It operates neighborhood circulator routes and Dial-A-Ride-style service in several outlying communities, with connections to Sun Tran routes where available.

Use the official trip planner or Transit app when you do not know the best route.
Open route
If you know the route, open the official Sun Tran/Sun Express route page or ride guide.

Use the official holiday page for major holidays because service differs by mode.
Common Sun Tran Schedule Mistakes That Make Riders Miss the Bus
Using the wrong service
The rider reads a fixed-route bus schedule when the trip needs Sun Link, Sun Shuttle or Sun On Demand.
Skipping alerts
The rider uses a normal stop even though construction has moved or discontinued service there.
Wrong direction
The rider reads the return direction instead of the direction toward their destination.
Holiday assumption
The rider assumes every holiday uses the same schedule, but Sun Express, Sun Link and Sun Shuttle can differ.
Ignoring service zones
The rider expects Sun On Demand or Sun Shuttle Dial-A-Ride where that service is not available.
No buffer time
The rider arrives at the stop exactly on the listed time and misses the bus or transfer.
