SAN FRANCISCO — A recurring Russian Hill Halloween street event is on San Francisco's 2026 traffic calendar again, with an SFMTA agenda listing Leavenworth Street Halloween for Saturday, Oct. 31 from 5 to 10 p.m.
The Oct. 8 agenda for the Interdepartmental Staff Council on Traffic and Transportation, or ISCOTT, lists a proposed temporary closure of Leavenworth Street between Lombard and Filbert streets, with the Leavenworth/Greenwich intersection closed during the same period.
There is one important qualification: the agenda is a proposal submitted for ISCOTT action. SF News Today has not yet verified the final 2026 vote from the meeting minutes, so this page is not describing the closure as approved at this stage.
What does SFMTA list for Leavenworth Street Halloween 2026?
The 2026 ISCOTT agenda lists:
Event: Leavenworth Street Halloween
Date: Saturday, Oct. 31, 2026
Time: 5–10 p.m.
Closure: Leavenworth Street between Lombard and Filbert streets
Intersection closed: Leavenworth at Greenwich Street
That places the event on the steep Russian Hill blocks immediately below the famous crooked section of Lombard Street.
Is the street closure approved?
That is the detail still being verified.
ISCOTT's Oct. 8 meeting is now in the past, and SFMTA has posted the meeting page and referenced materials. The agenda places Leavenworth Street Halloween on the consent calendar as a proposed temporary street closure.
Until the final disposition is confirmed from the minutes or a later SFMTA advisory, visitors and residents should treat the closure as listed/proposed, not as a final traffic order.
Where is the event?
The listed closure covers Leavenworth from Lombard Street south to Filbert Street, including the Greenwich Street intersection.
The block sits in Russian Hill, close to Lombard Street's tourist area but inside a residential neighborhood. If the closure proceeds, drivers should expect normal through access on that short Leavenworth segment to be interrupted during the five-hour event window.
What should residents and visitors expect?
At this stage, the primary 2026 public record establishes the event name, proposed block closure, date and time. It does not provide a detailed public program, entertainment schedule or organizer page.
That lack of a public-facing event page is precisely why the closure record is useful: someone searching for “Leavenworth Street Halloween 2026” may otherwise find older references without the current-year date and traffic footprint.
SF News Today will update this page if SFMTA publishes the final vote, a neighborhood organizer posts event details, or Muni issues a Halloween service advisory affecting the area.
Will Muni be rerouted?
No specific 2026 Muni reroute tied to this event has been verified yet.
The listed closure is only a short Leavenworth segment, but Halloween traffic and crowds can affect surrounding Russian Hill streets. Riders should check the SF News Today transit desk and SFMTA's same-day service alerts before traveling rather than assuming a route change that has not been announced.
When should drivers avoid the block?
If the closure is finalized as listed, the relevant period is 5–10 p.m. on Saturday, Oct. 31.
Residents needing vehicle access in the immediate blocks should watch for posted temporary no-parking notices and final SFMTA information as Halloween approaches.
