Find Pittsburgh Port Authority Bus Routes, Current Times, Stops and Live Arrivals
If you still search for the “Port Authority bus schedule” in Pittsburgh, the agency you need is now Pittsburgh Regional Transit, or PRT. Port Authority of Allegheny County was rebranded as Pittsburgh Regional Transit in June 2022, while the legal entity continues to use the Port Authority name in official documents.
This rider guide explains how to find a PRT route, read its timetable, check the current June 28, 2026 service changes, use TrueTime, understand fares and transfers, navigate the ReadyFare transition, and avoid missing important PDF footnotes such as pick-up-only or discharge-only stops.
Port Authority Bus Schedule Now Means Pittsburgh Regional Transit
For Pittsburgh and Allegheny County transit, use PRT’s official Schedule Finder. Select the exact route, then choose the correct direction and service day. PRT warns that scheduled times are approximate, and holidays can change the service level.
Do not confuse Pittsburgh with New York: if you mean the Port Authority Bus Terminal in Midtown Manhattan, you need the Port Authority of New York and New Jersey terminal information plus the individual bus carrier’s timetable. This page covers Pittsburgh Regional Transit.
I need a printed timetable
Open the PRT Schedule Finder, choose a route, then use the PDF option. Always check the effective service cycle before saving an older timetable.
I need the next bus
Use TrueTime with the route, direction and exact stop. A printed schedule cannot tell you whether the current vehicle is delayed.
I am going to the airport
Use 28X Airport Flyer. Its official PDF contains special boarding restrictions that are easy to miss in a simple timetable.
I need the fare
The current full stored-value and cash fare is $2.75, but cash is a single ride while eligible stored-value payment includes three hours of unlimited transfers.
My route looks different
Check PRT’s service-adjustment page. The current schedule cycle took effect June 28, 2026 and changed numerous routes.
I need Park and Ride
PRT maintains Park and Ride locations throughout Allegheny County. Most are free, but they are intended for commuter parking rather than overnight storage.
How to Find the Right Port Authority / PRT Bus Schedule
The route number is only the first step. A reliable lookup also requires direction, service day, destination and the correct stop.
Find the exact route name.
Enter the route number or name in PRT’s Schedule Finder. Similar-looking route labels can serve different corridors or operate only at certain times.
Choose the correct direction.
Match the destination printed on the vehicle. “Inbound” and “outbound” can be less useful when a route changes direction through Downtown.
Select weekday, Saturday, Sunday or holiday service.
Do not assume the Monday timetable applies on a federal holiday.
Locate your nearest timepoint.
Printed schedules show selected major stops rather than every stop along the route.
Identify the exact stop number.
PRT stop signs provide stop information that can be used with real-time tools.
Check TrueTime and detours before leaving.
The schedule is the plan; TrueTime and rider alerts help explain what is happening now.
PRT’s own Schedule Finder says all times are approximate. For a medical appointment, airport trip, job shift or timed connection, build in a buffer instead of planning to arrive at the stop at the exact printed minute.
Important PRT Bus Schedule Changes Riders Should Know
PRT says it adjusts schedules three times a year. The current cycle took effect Sunday, June 28, 2026, with another correction posted July 8 for one O12 trip.
The examples below are not every changed route. They highlight changes likely to matter when a rider is working from an older PDF, screenshot or saved trip.
28XAirport Flyer
Weekday and weekend schedules changed for on-time performance. The final Sunday inbound trip to Fifth Avenue Ramp now ends at 1:58 a.m. rather than 2:33 a.m.
Current weekday frequency: 43 min early AM, 27 AM peak, 31 midday, 30 PM peak, 29 evening and 41 late PM. Saturday and Sunday are published at 31 minutes all day.
51Carrick
Service was retimed between Carrick and the South Side. The final outbound trip to West Mifflin Garage is now earlier on weekdays, Saturdays and Sundays.
Weekday AM peak is now 7 minutes; the 4:00–6:15 p.m. peak period is about 8 minutes.
54North Side–Oakland–South Side
Weekday and Saturday schedules changed for crowding and reliability. The first weekday inbound trip to Allegheny Station now starts at 3:44 a.m.
Weekday AM peak changed to 18 minutes and PM peak to 19 minutes.
64Lawrenceville–Waterfront
Weekday and weekend schedules changed. The final weekday outbound trip to The Waterfront now ends at 1:46 a.m.; Saturday’s final outbound trip ends at 2:21 a.m.
Weekday PM peak is now 26 minutes, while late PM is 50 minutes.
75Ellsworth
The route now has a terminus at O’Hara VA Hospital. Service along Old Freeport Road was discontinued.
Saturday service is now published at 38 minutes all day. Sunday daytime periods are 39 minutes, with early and late periods at 52 minutes.
91Butler Street
Outbound trips now end at RIDC Park. O’Hara VA Hospital service moved to Route 75. Route 91 now uses Penn Station for its layover and outbound starting pattern.
Weekday AM peak is now 14 minutes; late PM is 40 minutes.
G2West Busway
The weekday schedule changed. The final weekday outbound trip to Carnegie Station now ends at 11:32 p.m., substantially earlier than the previous 12:28 a.m.
AM peak changed from 20 to 16 minutes; PM peak from 25 to 17 minutes.
P1East Busway All Stops
The weekday schedule changed to address peak-period crowding.
AM peak improved from 7 to 6 minutes. Early AM and late PM changed from 24 to 25 minutes.
Saved-PDF warning: if your schedule was downloaded before June 28, 2026, recheck it. A route number may be unchanged while the terminal, first trip, last trip, headway or stop pattern has changed.
There is no single “Port Authority frequency.” Service ranges from very frequent busway routes to longer-headway neighborhood and airport service.
The visual below compares selected current weekday AM-peak intervals from PRT’s June 28 service-adjustment information. A longer bar represents stronger service intensity, not a route-distance measurement.

Current PRT fare guide
Port Authority / PRT Bus Fares, Passes and Transfers
PRT’s current full stored-value fare is $2.75. Cash is also $2.75, but the benefit is different: stored-value payment is valid for three hours with unlimited transfers, while cash is valid for one ride.
Full Stored Value$2.753-hour transfer window
Unlimited eligible transfers during the three-hour validity period.
Cash Fare$2.75Single ride
Cash does not provide the same three-hour transfer benefit.
Half Fare$1.35Eligibility required
Stored-value half fare includes the three-hour transfer period.
Day Pass$7One service day
Valid from the beginning to the end of service during one day.
7-Day Pass$25Full fare
Valid for seven days after first use.
31-Day Pass$97.50Full fare
Valid for 31 days after first use.
Annual Pass$1,072.50365 days
Valid for one year after first use.
Seniors 65+FREEApproved senior ID required
Eligible riders use a Pennsylvania Senior Citizen ID or Senior ConnectCard.
Children 5 & underFREEWith fare-paying adult
PRT permits up to four free children age five and younger per paying adult.
Ages 6–11$1.35Kid’s ConnectCard
The published child fare is half the standard fare with the appropriate card.
Transfer example: a stored-value rider can board a bus, transfer to another PRT service and make additional eligible transfers within the same three-hour period without paying another full fare each time.
ConnectCard Is Moving to ReadyFare — What Riders Need to Know
PRT is transitioning from ConnectCard to its next-generation ReadyFare system. This is important because older online instructions may tell riders to use a fare machine or card workflow that is being replaced.
1
ConnectCard still works
PRT says riders can continue using ConnectCards during the transition.
2
ReadyFare rollout
New ReadyFare vending machines are replacing older ConnectCard machines at installed locations.
$1
ReadyFare card price
A ReadyFare card can be purchased for $1 from the new fare vending machines.
APP
Ready2Ride remains useful
Riders can use PRT’s Ready2Ride mobile system and link supported ReadyFare account information.
No confirmed ConnectCard cutoff date: PRT says it expects ConnectCards to stop being accepted sometime in late 2026, but it has not announced an exact date. Do not publish or rely on a made-up retirement date.
Bank-card tap warning: PRT’s ReadyFare FAQ says direct credit-card fare payment is not currently available, although the feature is planned for 2026. Do not assume you can simply tap a bank card at the validator today.
Where to tap ReadyFare
PRT instructs riders to tap the card on the black square on the lower half of the validator where the smart-card icon appears.
Senior ConnectCard users
PRT says senior riders do not need to take action yet and should continue using their Senior ConnectCard during the transition.
How to Use PRT TrueTime Without Misreading the Bus Schedule
A printed timetable and a live arrival prediction solve different problems. Use both when the trip matters.
PDF
Scheduled time
Shows when the bus is planned to reach a timepoint under the published schedule.
GPS
Arrival prediction
Uses current operating data to estimate when a vehicle will reach the selected stop.
MAP
Vehicle position
Helps show where a reporting vehicle is along its trip.
!
Service alert
Explains detours, stop closures and other disruptions that a vehicle map alone may not explain.
TrueTime limitation: a missing vehicle does not automatically mean the trip was canceled. GPS can stop reporting, a vehicle can be removed from service, or a detour can temporarily prevent the map from displaying the bus normally.
28X Airport Flyer: What the Official Schedule PDF Actually Shows
The official 28X PDF contains more than departure times. It includes route geography, West Busway stations, Oakland and Downtown airport stops, points of interest, park-and-ride symbols and special boarding restrictions.
The simplified SVG below translates the main trip pattern into a mobile-friendly route sequence. It is an explanatory visual, not a replacement for the official PRT map.
The Crucial 28X Boarding Rules Hidden in the PDF
Inbound toward Downtown / Oakland / Shadyside
Once the route reaches West Carson Street opposite Gateway View Plaza, inbound 28X trips become discharge only.
Outbound toward Pittsburgh International Airport
Outbound airport trips are pick-up only until the bus reaches Robinson Town Centre at Park Manor Boulevard.
Robinson Town Centre
The PDF states that Robinson Town Centre stops are served for both pick-up and discharge.
Why this matters: seeing a 28X bus physically stop does not guarantee that you may board or exit there in the direction you want. The airport route uses special passenger-flow rules.
Selected Oakland Stops for the Airport
Street
Official PDF Stop Locations

Past Morewood Avenue; at South Craig Street; at Dithridge Street
Boulevard of the Allies
Marion Street near Mercy Hospital.
Seventh Avenue

Liberty Avenue
Stops include Tito Way, Fifth Avenue and a location near the Wyndham Grand Hotel.
West Busway nuance: the official route map states that inbound 28X stops at Bell, Idlewood, Crafton, Ingram and Sheraden allow both pick-up and discharge. Outbound West Busway stops toward the airport are pick-up only.
28X PDF
Official 28X Airport Flyer Schedule and Map
This is the PRT source document used for the stop-policy and route visual above. It includes Monday–Friday, Saturday, Sunday/holiday timetables and a detailed route map.
The PDF is linked from PRT’s current June 28, 2026 service-adjustment material. Open the current service page as well before travel in case PRT replaces the document.
How to Read a PRT Bus Timetable Without Missing Your Trip
A timetable column is a trip
Follow one trip down or across the schedule rather than combining times from different rows or columns.
Timepoints are selected stops
A printed schedule does not need to list every bus stop. Use the closest earlier timepoint and live stop information for an intermediate stop.
Direction matters
The return trip may be shown in a separate timetable or opposite-direction panel.
AM and PM formatting matters
The 28X PDF uses light type for AM times and bold type for PM times. Read the legend before assuming formatting is decorative.
Footnotes can override the obvious answer
A trip may be pick-up only, discharge only, short-turn, limited or restricted to a specific service day.
Terminal names can change
Route 75 and Route 91 demonstrate why an old terminal name can send a rider to the wrong place after a service change.
Best practice: read the route name → direction → day → footnote → timepoint → live arrival, in that order.
Fast corridor guide
Understanding PRT Busway Routes
Pittsburgh’s busway network can make regional trips faster by separating buses from much of the regular street traffic. Route labels such as P1 and G2 are important because the letter is part of the route identity.
P1 East Busway All Stops
Current June 2026 weekday AM-peak frequency is published at about six minutes.
G2 West Busway
Current weekday peak service is about 16 minutes in the AM peak and 17 minutes in the PM peak.
28X and the West Busway
The airport route uses West Busway stations but applies direction-specific pick-up/discharge rules.
Do not shorten the route label: P1, P12, P16, P67 and P71 are different services. Searching only for “P bus” is not enough.
Upcoming 2026 holiday service
Does the Port Authority Bus Run on Holidays?
Yes, PRT operates bus and rail service on holidays, but the service level may change. Some holidays use Sunday bus schedules while others retain regular weekday service.
Labor Day
Bus service uses Sunday schedules.
Veterans Day
Bus service uses regular weekday schedules.
Thanksgiving Day
Bus service uses Sunday schedules.
Christmas Day
Bus service uses Sunday schedules.
Holiday trap: a route that normally operates Monday may have a Sunday-level timetable on a Monday holiday. Check the holiday page rather than looking only at the calendar weekday.
PRT Park and Ride: When Driving Part of the Trip Makes Sense
PRT provides Park and Ride locations throughout Allegheny County, and the agency says most are free.
Use for commuter parking
PRT states that its Park and Ride lots are intended for commuter use, not residential, commercial or general long-term storage.
Do not assume overnight parking
Overnight and long-term parking are generally restricted unless a particular facility has different rules.
Park only in designated areas
Parking outside the approved area can place the vehicle at risk of a ticket or tow.
Airport-trip caution: do not leave a car at a PRT Park and Ride for an extended vacation merely because your 28X trip reaches the airport. Verify the individual lot’s parking rules first.
PRT states that all of its buses and light-rail vehicles, along with the Monongahela Incline, are ADA-compliant. Every PRT bus is equipped with a ramp.
You can request the ramp
PRT says a rider does not have to use a wheelchair or mobility device to request the bus ramp when it makes boarding or exiting safer.
Vehicle access is not stop access
An accessible bus does not guarantee that every temporary or permanent stop has an equally easy sidewalk, curb or boarding surface.
Plan transfers carefully
When connecting to rail, a busway station or another route, verify accessibility of the complete transfer path rather than the bus alone.
PRT’s Lost and Found form asks for details that can connect the item to a specific vehicle and trip.
Record the route.
Write down the complete bus route number or name.
Record the four-digit vehicle ID if you have it.
This can substantially narrow the search.
Provide the date and approximate time.
Include where you boarded and where you got off when possible.
Describe the item specifically.
Give color, brand, material and unique identifying details.
Provide contact information.
PRT uses the submitted information to contact you if the property is turned in.
Protect sensitive items immediately: lock a lost phone and suspend or cancel financial cards rather than waiting for the transit lost-property process.
The bus is missing from TrueTime
Check the printed trip and current alerts. A vehicle can disappear from real-time tracking because of lost location data, detour behavior or an operating change.
The PDF and website disagree
Look for the PDF’s service date. Give priority to the current official Schedule Finder and service-adjustment information.
The bus stopped but would not let you board
Check whether the trip is pick-up only or discharge only. The 28X uses these restrictions on portions of its airport routing.
Your route no longer reaches the old terminal
Check the June 28 changes. Route 75 and Route 91 changed terminal/service responsibilities around O’Hara VA Hospital.
You arrived on a holiday and no bus came
Check whether PRT is operating Sunday schedules for that holiday.
You cannot find a stop in the printed timetable
The timetable lists timepoints rather than every stop. Use the route map and stop-level tools.
Your bank card will not tap
Do not assume open-loop credit-card fare payment is live. PRT’s ReadyFare FAQ says this feature is planned but not currently available.
Your ConnectCard still works
That is expected during the 2026 ReadyFare transition. PRT has not published an exact final ConnectCard acceptance date.
Search-intent disambiguation
Looking for the New York Port Authority Bus Terminal Instead?
The phrase “Port Authority bus schedule” can also mean the Midtown Manhattan bus terminal operated by the Port Authority of New York and New Jersey.
That terminal hosts multiple carriers. The terminal itself is not the same thing as a Pittsburgh Regional Transit route schedule, so identify the carrier and destination before using a timetable.
Pittsburgh search: use PRT / rideprt.org. New York–New Jersey terminal search: use the PANYNJ bus-terminal information and the schedule of the carrier operating your trip.

Frequently Asked Questions About the Port Authority Bus Schedule
Is Port Authority now called Pittsburgh Regional Transit?
Yes. Port Authority of Allegheny County was rebranded as Pittsburgh Regional Transit, or PRT, in June 2022. Many riders still search the former Port Authority name.
Where can I find a PRT bus schedule?
Use the official PRT Schedule Finder, select the exact route and then check the direction, service day and PDF or visible timetable.
Are PRT bus schedule times exact?
No. PRT’s Schedule Finder states that all times are approximate. Use TrueTime and current service alerts before an important trip.
How much is a Pittsburgh Regional Transit bus fare?
The current full stored-value fare is $2.75 and includes three hours of unlimited transfers. The $2.75 cash fare is valid for a single ride.
Can I still use a ConnectCard in 2026?
Yes. PRT says ConnectCards remain accepted during the ReadyFare transition. The agency expects acceptance to end sometime in late 2026 but has not published an exact cutoff date.
Can I tap a credit card directly to pay a PRT fare?
PRT’s ReadyFare FAQ says direct credit-card fare payment is not currently available, although it is planned for 2026.
Which PRT bus goes to Pittsburgh International Airport?
The 28X Airport Flyer provides PRT service to Pittsburgh International Airport. Check its current timetable and special pick-up/discharge rules before boarding.
Why can’t I board a 28X bus at every stop?
The route uses direction-specific stop restrictions. Airport-bound trips are pick-up only through portions of the route, while inbound trips become discharge only after reaching West Carson Street opposite Gateway View Plaza.
Does PRT operate on holidays?
Yes, but the service level varies. Several major holidays use Sunday bus schedules while others use regular weekday schedules.
Why did my usual PRT route change?
PRT adjusts schedules periodically. The current major schedule cycle took effect June 28, 2026, changing times, frequencies or terminal patterns on numerous routes.
Does every PRT bus have wheelchair access?
PRT states that all of its buses are ADA-compliant and equipped with ramps. Accessibility of the physical boarding stop should still be checked separately.
Can I take a bicycle on a PRT bus?
Yes. Each bus has a front-mounted rack for two bicycles. PRT publishes size and loading restrictions, and riders are responsible for loading and unloading their own bicycle.
What information should I give PRT Lost and Found?
Provide the route, four-digit vehicle ID if known, the travel date and approximate time, a detailed item description and your contact information.
Is this the same Port Authority as the New York Port Authority Bus Terminal?
No. This guide covers Pittsburgh Regional Transit, formerly Port Authority of Allegheny County. Midtown Manhattan bus-terminal information is handled through the Port Authority of New York and New Jersey and the individual bus carriers.
