Sun Tran Bus Schedule: Routes, Times & Stops

Sun Tran bus schedule searches usually mean one of three things: finding the right Tucson route, checking the next bus time at a specific stop, or confirming whether a detour, holiday schedule, or August service change affects today’s trip.

This guide explains Sun Tran routes, schedule lookup, free fares, Transit app live arrivals, Sun Express, Sun Link, Sun Van, Sun Shuttle, Sun On Demand, major transit centers, accessibility, holiday service, and same-day alert checks.

How to Find the Right Sun Tran Bus Schedule

Sun Tran operates regular fixed-route bus service in Tucson and nearby communities. The fastest way to get the correct bus time is to start with your route number or destination, select the right direction, confirm the stop number, then check the Transit app or official Sun Tran route page for the live or scheduled time.

1
Search route

Use route number, street, transit center, school, hospital, mall, or destination.

2
Pick direction

A route may serve the same corridor in both directions from different stop sides.

3
Check schedule

Use the route page, ride guide, or app for weekday/weekend timing.

4
Check alerts

Detours can skip stops, move stops, or change travel time.

5
Track live

Use the Transit app before walking to the stop.

Fare note: Sun Tran, Sun Express, Sun Link, Sun Van, Sun On Demand, and Sun Shuttle rides are currently fare-free at the direction of Mayor and Council. Still check the official fare page before publishing or traveling because fare policy can change.

Sun Tran Bus Schedule Guide

Routes overview

Sun Tran Routes: What the Route List Actually Means

Sun Tran route pages are useful because they do more than name the bus route. They show route number, route name, whether it is part of the Frequent Transit Network, cities served, transit centers served, park-and-ride connections, major destinations, and the official schedule link.

Core Tucson routes Routes such as 1 Glenn/Swan, 2 Tucson Marketplace, 3 6th St./Wilmot, 4 Speedway, 5 Pima/W. Speedway, 6 Euclid/N. 1st Ave., 7 22nd St., 8 Broadway, 9 Grant, 10 Ruthrauff, 11 Alvernon/Ajo, and 12 S. 12th Ave. connect many central Tucson destinations.
Frequent corridors Some routes are marked as Frequent Transit Network routes. These are usually better for riders who need shorter waits, but you still need the exact route schedule because frequency can change by day and time.
Transit-center routes Ronstadt, Roy Laos, and Tohono Tadai Transit Centers are key transfer points. If a route serves a transit center, check the bay, posted stop sign, and transfer route before boarding.
Sun Express Sun Express routes are commuter-focused, limited-stop routes that generally operate on weekdays during peak commute hours. Do not assume a Sun Express route runs like a regular all-day local route.
Sun Shuttle Sun Shuttle connects communities such as Oro Valley, Catalina, Marana, Sahuarita, Green Valley, Tucson Estates, San Xavier, Rita Ranch, and Ajo-Tucson with regional transit links.
Sun On Demand Sun On Demand provides curb-to-curb rides inside designated zones and can connect riders to Sun Tran bus stops, Sun Link, and other transit services.
August 2026 service-change warning: Sun Tran, Sun Express, and Sun Shuttle implemented route and schedule changes starting August 16, 2026. Routes including 2, 3, 4, 5, 7, 8, 9, 11, 15, 16, 19, 34, 37, 61, 62, and 124X received schedule adjustments. Always use the current route page or the August 16, 2026 booklet.
Times and frequency

How to Read Sun Tran Bus Times Correctly

Sun Tran schedules are route-specific and stop-specific. The time shown in a route timetable is usually a timepoint, not every bus stop. Your exact stop may be between two timepoints, so use the live app or trip planner to avoid guessing.

What you are checking Best source What to look for Rider tip
First bus Official route schedule or Transit app First trip from the correct direction and stop, not only the first bus from a terminal. Check weekday, Saturday, Sunday, and holiday separately.
Last bus Official route schedule Last trip from your actual stop or transfer point. Plan the return trip before leaving, especially at night.
Frequency Route page and ride guide Frequent Transit Network label, peak/off-peak spacing, evening spacing, weekend spacing. If times are irregular, do not rely on “every 15 minutes” from a snippet.
Live arrival Transit app / official trip planner Predicted arrival at your stop, route direction, and alert icons. Refresh before walking because live predictions can change.
Transit app live stop time Best
Official route schedule Good
Ride guide booklet Useful
Old PDF or screenshot Avoid
Approximate arrival rule: arrive at the stop at least 5 minutes early. Use more time for transfers, unfamiliar stops, summer heat, mobility needs, high-ridership corridors, or routes with long headways.
Ticket price and fare rate

Sun Tran Fare: Rides Are Currently Free

Sun Tran’s current fare page says all transit rides remain fare-free. That includes Sun Tran, Sun Link, Sun Van, Sun On Demand, Sun Express, and Sun Shuttle. Riders should still check the official fare page because this is a policy decision and may change.

Sun Tran local bus $0 Currently fare-free

Board normally and check the route, direction, and stop. If fares return later, verify the accepted payment method before boarding.

Sun Express $0 Currently fare-free

Sun Express is still commuter-style service, so schedule and service day matter even while fares are waived.

Sun Link Streetcar $0 Currently fare-free

Useful for Downtown Tucson, 4th Avenue, Main Gate Square, and University of Arizona connections.

Sun Van $0 Currently fare-free

Sun Van is ADA paratransit for eligible riders and has a separate eligibility process.

Sun On Demand $0 Currently fare-free

Use the service only inside designated zones and follow booking/pickup rules.

Sun Shuttle $0 Currently fare-free

Sun Shuttle schedules and dial-a-ride details vary by community, route, and service type.

Do not publish old fare tables: older SunGO/cash fare PDFs may still appear online, but the current fare page says rides remain free. Always use the current fare page for the live policy.
Stops and route map

Sun Tran Stops: Use the Stop Number, Not Only the Street Name

Sun Tran stop signs include route numbers, a bus stop number, customer service information, and signage that helps riders use online trip planning and next-bus arrival tools. This is important because the same road can have stops on both sides, and a route can have detours that skip only one direction.

Common Tucson transfer pattern

Stop-side tip: if your bus travels both directions on the same corridor, the return stop may be across the street. Always match the route number, direction, and stop number before trusting the next-arrival time.
Transit centers

Major Sun Tran Transit Centers

Tucson has three major Sun Tran transit centers: Roy Laos, Ronstadt, and Tohono Tadai. These are useful for transfers, but the correct bus bay can matter as much as the route number.

Ronstadt Transit Center Downtown Tucson hub. It serves many Sun Tran routes, several Sun Express routes, Sun Shuttle 421X, and is within walking distance of Sun Link streetcar connections.
Roy Laos Transit Center South-side hub. It serves routes such as 12, 16, 23, 26, 27, 29, several Sun Shuttle routes, and nearby Sun Express connections.
Tohono Tadai Transit Center Northwest-side hub. It serves routes such as 6, 15, 16, 17, 19, 34, 61, 62, and Sun Shuttle 412, with park-and-ride access.
Transit-center tip: customer service representatives are listed at Laos and Ronstadt during weekday business hours. If your route changed bays after a service change, check posted signs and the official route page.
Google Map example

Example Map: Ronstadt Transit Center, Downtown Tucson

Ronstadt Transit Center is the best map example for a system-wide Sun Tran schedule page because many city routes and express routes connect there. Use this map for walking orientation only; Sun Tran controls the official route, stop number, bay, and live arrival information.

  • Confirm your route number before entering the center.
  • Check the bus bay or stop number.
  • Use the Transit app for live arrival.
  • Check alerts before walking to a moved stop.
Live bus tools

Scheduled Time vs Live Sun Tran Arrival

Scheduled time is the planned timetable. Live arrival is the same-day prediction in the Transit app or trip planner. Live arrival can change because of traffic, detours, weather, operator availability, construction, event congestion, or real-time data issues.

1
Open Transit

Use Sun Tran’s official Transit app or trip planner.

2
Allow location

Nearby routes and next departures become easier to compare.

3
Search route

Enter route number, destination, address, school, or transit center.

4
Select stop

Use stop number, stop name, or map pin before trusting the time.

5
Use GO

GO can provide step-by-step audio and visual trip guidance.

Alerts and detours

Check Sun Tran Alerts Before You Leave

Regular service holidays Some listed holidays operate on a regular schedule. Check the holiday page for the current year.

Sun Express warning Sun Express may have no service on several holidays even when other transit services operate.
Accessibility

Sun Tran Accessibility Details to Check

Sun Tran states that all buses offer accessibility features for riders requesting service. Still, a rider should check both the vehicle and the stop because a curb, sidewalk, construction zone, weather issue, or temporary stop can affect real-world boarding.

Ramps and lifts Sun Tran buses are equipped with lifts or ramps for boarding ease.
Kneeling buses Buses can kneel to make boarding more convenient. Ask the operator if needed.
Announcements Sun Tran buses include annunciators for major stops, cross streets, and transfer locations.
Boarding spacing If using the lift or ramp, stay back so the equipment can be lowered safely.
Accessible arrival tip: Sun Tran accessibility guidance says to arrive at the stop at least five minutes early and wait where the driver can see you.
Rider tricks

How to Avoid Missing a Sun Tran Bus

Use the stop number A street name alone is not enough. Use the stop sign, stop number, map pin, or app stop listing.
Check the return trip first Evening, Sunday, and holiday service may be different from your outbound trip.
Do not ignore detours A route can operate normally in one direction while one stop or street segment is skipped.
  • Confirm Sun Tran, Sun Express, Sun Shuttle, Sun Link, Sun Van, or Sun On Demand.
  • Use the official route page or August 16, 2026 booklet.
  • Choose weekday, Saturday, Sunday, or holiday schedule.
  • Pick the correct direction before reading the times.
  • Use stop number and stop side, not only a landmark.
  • Open the Transit app for live arrivals.
  • Arrive at least 5 minutes early.
  • Use extra time for transit centers, transfers, heat, or mobility needs.
  • Check alerts for detours or missed stops.
  • Plan your last bus or return trip before you leave.
