USA Route 31 Schedule & Stop Finder

Choose the Right Route 31 Before You Read the Timetable

Route 31 is not one national bus line. Chicago, San Diego, Seattle, Fort Collins, Cleveland and Kansas City all use the number 31 for different streets, terminals, fares and operating patterns.

Use this guide to identify the correct transit agency first, then check its official times, stops, map, fare, live arrival tool, service exception and printable schedule.

Quick answer

Which 31 Bus Schedule Are You Looking For?

The route number is only the first clue. The correct schedule depends on the city, agency, destination and service day.

Find the city Chicago’s 31 serves 31st Street. San Diego’s 31 connects Mira Mesa and UTC. Seattle’s 31 links Magnolia with the University District corridor.
Find the operator Match CTA, MTS, King County Metro, Transfort, GCRTA, RideKC or another local agency.
Read the destination Route 31 buses can have branches, short turns or different terminal patterns. The destination sign matters.
Check today’s service type Some Route 31 services run every day, some are weekday-only and Fort Collins Route 31 operates only when CSU is in session.
Do not search by “31” alone. Route 31 in Cleveland, Seattle and Chicago are unrelated services even though they share the same route number.
This page is a representative national finder, not a claim that these are the only Route 31 buses in the United States. If your city is not listed, open your local transit agency and search its current Route 31 page.

RideKC 31 31st Street — Kansas City, Missouri

RideKC Route 31 follows the 31st Street corridor with service toward MCC-Penn Valley and eastern Kansas City destinations.

Route 31 Changes Riders Should Check Before Leaving

Schedule pages often stay online for years. These current-date checks are more important than simply finding a PDF with “31” printed on it.

Seattle Route 31 Temporary stop relocation Stop #25202 at NE 45th Street & University Village is temporarily relocated during construction through late August 2026. Use the temporary westbound stop just east of the University Village main driveway.
Fort Collins Route 31 Campus-service check Route 31 runs only when CSU is in session. Transfort also has system changes taking effect in mid-August 2026, so reopen the route page before the first fall-semester trip.
CTA Route 31 Old printable PDF CTA’s live route page is current, but its printable Route 31 document is marked effective September 3, 2019. Use the route page and tracker for current-day decisions.
RideKC Route 31 Fare system changed RideKC restored bus fares on June 1, 2026. Older pages describing Kansas City buses as universally fare-free should not be used for current travel.
Cleveland Route 31 Current published PDF GCRTA continues to publish Route 31 using the schedule marked effective June 8, 2025. The route includes weekday, Saturday and Sunday/holiday tables.
San Diego Route 31 Use date selector MTS publishes trip-level times through its interactive schedule. Select the real travel date, direction and boarding stop rather than saving one dated trip URL.

Why “31 Bus” Can Mean Six Very Different Trips

This SVG is a route-selection diagram, not a geographic map. Its purpose is to prevent riders from using the timetable for the wrong transit agency.

Operating-pattern comparison

Route 31 First Bus, Last Bus and Service Days

Agency Route Published Pattern What Riders Must Check
CTA Chicago 31 31st Weekdays; about 7:00 a.m.–7:00 p.m. eastbound and 6:30 a.m.–7:00 p.m. westbound from origin terminals Mid-route stops are later; no normal weekend Route 31 schedule is published
San Diego MTS 31 UTC–Mira Mesa Date- and direction-specific interactive schedule Select the exact travel date and direction
King County Metro 31 Weekday, Saturday and Sunday tables Current service period ends August 28, 2026
Transfort 31 CSU Loop About every 10 minutes, Monday–Friday when CSU is in session University break and holiday exceptions
GCRTA Cleveland 31 St. Clair–Babbitt Weekday, Saturday and Sunday/holiday service Only selected trips serve Amazon-Euclid
RideKC 31 31st Street Weekday, Saturday and Sunday Some late-night trips use a shorter terminal pattern
Terminal span is not your stop time. If the first bus leaves the terminal at 6:30 a.m., a stop several miles away will be served later.
Official timetable examples

Useful Route 31 Departure Examples

These examples explain how the official timetables behave. They are not a substitute for checking the date-specific schedule immediately before travel.

Chicago eastbound CTA’s current route page states that buses leave Ashland Orange Line station for 33rd Place/King Drive from about 7:00 a.m. through 7:00 p.m. on weekdays.
Chicago westbound CTA publishes origin-terminal service from 33rd Place/King Drive toward Ashland from about 6:30 a.m. through 7:00 p.m. on weekdays.
San Diego early trip A recently reviewed MTS weekday trip toward UTC leaves Miramar College Transit Station at 5:39 a.m.; the next stops appear shortly afterward on Black Mountain Road.
Seattle morning example The current Metro table shows Route 31 leaving South Magnolia at 6:47 a.m., reaching Seattle Pacific University about 13 minutes later and University District Station later in the trip.
Fort Collins loop The printable Transfort Route 31 timetable is designed around 10-minute departures from CSU Transit Center during its operating period.
Cleveland early service GCRTA’s current published timetable includes eastbound departures from Stokes-Windermere beginning before 4:00 a.m. and continuing across the day.
Kansas City inbound RideKC’s weekday table begins with an inbound departure from the eastern Route 31 corridor at 4:27 a.m.
Kansas City late pattern Late weekday departures from 31st/Pennsylvania include trips around 11:08 p.m., 11:38 p.m. and 12:08 a.m. using the shorter Van Brunt pattern.
Why examples matter They expose branch and service-pattern differences without forcing a rider to decode hundreds of timetable cells before understanding the route.

How Much Does the 31 Bus Cost?

There is no universal Route 31 fare. Payment is controlled by the local transit agency.

CTA Chicago $2.25 Regular bus fare using Ventra value CTA’s current fare chart lists a $2.25 regular bus fare. Cash on the bus is $2.50 and does not provide a transfer.

Verify CTA fares

San Diego MTS $2.50 Adult one-way bus fare PRONTO payment includes unlimited transfers for two hours. A cash one-way bus fare does not provide the same transfer benefit.

Payment rules matter as much as the price. Cash can remove transfer privileges on some systems, while account-based cards and apps may provide transfers or fare capping.

How to Find the Correct Route 31 Stop

Agency Confirm the operator.
Route Match 31 exactly.
Direction Read the destination.
Stop ID Save the number.
Street side Confirm the curb.
Alert Check relocation.
Open the official route map. A third-party route screenshot may be old and may not show temporary stop changes.
Choose the final destination. Use the bus headsign, not simply “eastbound” or “westbound,” when the service has branches or partial trips.
Find the exact stop or timepoint. Intersections can have stops on multiple corners for different directions.
Look for a temporary relocation. Seattle Route 31 currently has a construction-related relocation affecting the University Village area.
Check whether your trip serves the stop. Cleveland’s Amazon-Euclid deviation and Chicago short-turn trips are examples where not every trip follows the full pattern.
Track the approaching bus. Verify both the number 31 and the destination before boarding.

Official-document interpretation

What the Route 31 PDFs Tell Riders That a Simple Stop List Does Not

CTA short-turn trips The CTA document warns riders to watch destination signs because some trips can end before the furthest terminal. Its timetable specifically identifies trips that end at 35th/Wentworth or Sox-35th.
CTA accessible connections The document identifies connections to the Ashland Orange Line, Sox-35th Red Line and 35th-Bronzeville-IIT Green Line corridor and states that all CTA buses are accessible.
Transfort timepoints The Route 31 PDF distinguishes scheduled timepoints from ordinary stops. Timepoints are the safest printed reference for estimating an intermediate stop arrival.
Transfort loop timing A typical scheduled loop is designed to return to CSU Transit Center after passing City Park/Plum, Constitution/Elizabeth and Plum/Scott.
Cleveland Amazon deviation The GCRTA timetable contains an Amazon-Euclid column, but many rows contain a dash. That means only selected Route 31 trips make that deviation.
Cleveland holiday rule GCRTA publishes Sunday/holiday service for New Year’s Day, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas.

A dash can be meaningful In the Cleveland Route 31 timetable, a dash in the Amazon column means that trip does not travel through the Amazon-Euclid deviation.
Combined route tables need attention King County Metro publishes Routes 31 and 32 together. Always read the route-number column before selecting a departure.
A late trip can have a shorter route RideKC Route 31 has late-night trips with a shorter Van Brunt terminal pattern.
School-term service is different Transfort Route 31 can disappear completely during CSU breaks rather than merely running less frequently.
Old PDF, current route A route can remain active while its printable PDF carries an older effective date. CTA Route 31 is a clear example.

Real-World Route 31 Trip Planning

Chicago rail connection If connecting to the Orange Line, work backward from the Ashland terminal time and allow extra walking time between the bus stop and station entrance.
San Diego morning commute Choose the actual MTS travel date because trip times are generated by date. Save the correct Mira Mesa or UTC direction before leaving home.
Seattle hospital trip Route 31 reaches the Seattle Children’s/Laurelhurst area. Check the current University Village stop relocation before a medical appointment.
CSU class trip A 10-minute campus frequency is useful only when Route 31 is actually in service. Check the CSU academic-service exception before relying on it.
Cleveland Amazon trip Do not board every Route 31 expecting the Amazon deviation. Match a trip that contains an Amazon-Euclid time in the official table.
Kansas City late trip Check the destination carefully late at night because some Route 31 departures do not follow the same terminal pattern as daytime service.

Before You Leave for a Route 31 Stop

  • Confirm the city and transit agency.
  • Open the current official Route 31 page.
  • Check the timetable effective date.
  • Select the correct service day.
  • Match the bus destination.
  • Save the stop ID or station bay.
  • Check for short turns or route deviations.
  • Check active stop relocations.
  • Check the live arrival prediction.
  • Prepare the correct fare or transit card.
  • Allow transfer time.
  • Save the agency contact number.

Route 31 Problems and What to Do

The PDF and live page disagree Use the current official route page as the primary source. CTA Route 31 is a good example because its linked PDF is much older than the live page.
The bus is not coming in Fort Collins Check whether CSU is in session. Route 31 is not a normal year-round all-day route.
The Seattle stop is missing Check Metro’s active stop-relocation notice. Construction can move the westbound University Village-area stop.
The Cleveland bus skipped Amazon Not every Route 31 trip serves Amazon-Euclid. Look for a scheduled time in that column.
The Kansas City bus ends early Late-night Route 31 trips can use a shorter terminal pattern. Read the complete trip heading.
The live prediction disappeared Check agency alerts and the next scheduled departure. GPS reporting can disappear even when service is still operating.
The fare you remembered is wrong Recheck the official agency fare page. RideKC changed from fare-free service to paid bus fares on June 1, 2026.
The PDF will not display Open it directly in a new tab. Some agency servers or mobile browsers prevent iframe viewing.
