Muni riders on a dozen routes will see new schedules beginning Saturday, Aug. 29. Some changes are small on paper — a one-minute reduction in scheduled headway — while others change the size of the bus, school-trip pattern or time of day when extra capacity appears.
SFMTA says the package affects the K Ingleside, N Judah, 1 California, 5R Fulton Rapid, 8AX Bayshore A Express, 22 Fillmore, 28R 19th Avenue Rapid, 29 Sunset, 37 Corbett, 38R Geary Rapid, 49 Van Ness/Mission and 66 Quintara.
The agency's own description is important: these are not 12 identical service increases. Some routes get more frequent scheduled service, some get larger vehicles, and some are being reshaped around schools or observed travel times.
The 1 California and N Judah get slightly shorter waits
The 1 California is scheduled every nine minutes instead of every 10. SFMTA says the overlapping service between the Presidio and downtown should produce a bus roughly every four to five minutes on that shared segment.
Peak-period N Judah service also moves from 10-minute to nine-minute scheduled headways. SFMTA says it is pairing the change with operational adjustments at the La Playa terminal intended to reduce congestion and improve reliability.
A one-minute headway change can sound trivial, but on high-ridership routes it also means more trips and more carrying capacity over the course of a peak period. Whether riders actually experience the scheduled improvement will depend on bunching, traffic and operating conditions after the new timetable begins.
The 5R gets bigger buses on every trip
The 5R Fulton Rapid is a different case. Its schedule will be every 10 minutes, but SFMTA says every trip will operate with a 60-foot articulated bus rather than the current mix of 40- and 60-foot vehicles.
That is an important distinction for riders: the improvement is primarily capacity, not frequency. A line can carry more people without showing a dramatically shorter wait on a timetable.
SFMTA is also assigning targeted additional capacity to the 22 Fillmore and 29 Sunset, with morning-peak additions on the 38R Geary Rapid and 49 Van Ness/Mission and evening capacity on the 29.
Several changes are really school-service changes
A handful of morning 8AX trips will continue north of Broadway on regular 8 Bayshore stops, giving riders from Visitacion Valley a one-seat trip to Francisco Middle School rather than requiring a transfer.
The 28R will add a stop at 19th Avenue and Eucalyptus Drive, closer to Lowell High School. SFMTA is also reorganizing trips involving the 37 Corbett, 66 Quintara and K Ingleside around Hoover, Rooftop and Aptos middle schools.
Those details matter more to a family using a particular school trip than the systemwide headline. Riders who depend on a school-day run should compare their existing trip with the Aug. 29 schedule rather than assuming the route works exactly as it did in spring.
The overnight 22 changes time, not frequency
The 22 Fillmore Owl will continue to run every 30 minutes between midnight and 5 a.m., but departure times will be adjusted to better match observed travel times. That is a schedule correction, not a cut in overnight frequency.
SFMTA says the package costs no additional operating money
The agency says the Aug. 29 changes are cost-neutral, using schedule efficiencies and existing resources to put capacity where it sees higher demand. In a separate release, SFMTA said it has identified approximately $250 million in systemwide savings since 2025.
That makes this service change more than a timetable footnote. It shows how Muni is trying to improve selected high-demand trips while operating under severe budget pressure: more capacity in some places without adding to total operating cost.
The next test is empirical. Once the schedules are live, riders can compare the promised nine-minute service and larger 5R buses with actual arrivals.
