SAN FRANCISCO — Dreamforce is still more than a week away. The traffic footprint arrives this weekend.
SFMTA says partial street restrictions around Moscone Center begin at 10 p.m. Friday, Sept. 4, followed by a full closure of Howard Street between Third and Fourth streets at 6 a.m. Saturday, Sept. 5.
That block of Howard is scheduled to remain closed continuously until 10 p.m. Sunday, Sept. 20 — three days after Dreamforce itself ends.
Salesforce’s annual conference runs Sept. 15–17 at Moscone Center. The unusually early closure means SoMa drivers, delivery workers, nearby residents and anyone heading through the Moscone area will feel part of the event footprint about 10 days before badge-holders arrive for the first full conference day.
The first restrictions start Friday night
From 10 p.m. Friday to 3:30 a.m. Saturday, SFMTA lists partial closures on:
- southbound Fourth Street between Minna and Howard
- northbound Fourth Street between Folsom and Mission
- Third Street between Mission and Folsom
Those same overnight restrictions are scheduled again after the conference, from 10 p.m. Sept. 17 to 3:30 a.m. Sept. 18.
The longer-duration closure begins a few hours later.
Howard Street closes Saturday morning
From 6 a.m. Saturday, Sept. 5 through 10 p.m. Sunday, Sept. 20, Howard Street is fully closed between Third and Fourth streets.
Over the same period, SFMTA lists partial closures on:
- Howard between Hawthorne and Third
- Third between Folsom and Mission
- Folsom between Third and Fifth
- Fourth between Howard and Folsom
This is the core build-out period for the area Salesforce calls Dreampark on Howard Street between Third and Fourth.
Salesforce says Dreampark remains closed to attendees until 7 a.m. Sept. 15 and then becomes badge-only space during the conference.
More closures arrive as Dreamforce gets closer
The weekend restrictions are only the first layer.
SFMTA says additional closures begin in the days immediately before the conference, including daytime full closures of Minna between Fourth and Fifth and Fourth between Mission and Howard from Sept. 14 through Sept. 17.
A broader partial closure on Fourth between Minna and Folsom begins at 10 p.m. Sept. 13 and continues through the evening of Sept. 17.
There are also time-specific restrictions on Howard west of Fourth during conference commute periods.
For a driver, the practical point is that the traffic pattern around Moscone gets progressively tighter from this weekend through conference week rather than changing all at once on Sept. 15.
Will Muni reroute for Dreamforce?
SFMTA says no Muni reroutes are currently required for the event.
The agency plans to keep regular routing and regular bus stops on Stockton and Fourth Street, although it warns of possible minor delays in the area because of congestion and pedestrian activity.
Routes listed by SFMTA as serving the affected area include the T Third, 8/8AX/8BX Bayshore services, 15 Bayview Hunters Point Express, 30 Stockton, 45 Union/Stockton and 91 Owl.
For Moscone itself, one of the simplest rail options is the T Third to Yerba Buena/Moscone Station. BART riders can also use Powell Street and walk toward Moscone or transfer through the Central Subway.
What about parking garages?
SFMTA says major garages in the area remain open, including Fifth & Mission, Moscone Center and Ellis-O’Farrell.
That does not mean driving will be convenient. Garage access can remain technically open while nearby blocks have detours, lane restrictions and unusually heavy pedestrian traffic.
Anyone parking near Moscone during the build-out and conference should allow extra time and approach from a route that does not depend on crossing the closed Howard block.
Why does Howard close so early?
Dreamforce uses the block of Howard between Third and Fourth as more than a roadway during the event. Salesforce identifies the area as Dreampark, part of the secure conference footprint between Moscone buildings.
Transforming a public street into event space requires build-out and later teardown, which is why the closure extends far beyond the three formal conference days.
This year, the full Howard closure begins Sept. 5, while Dreamforce starts Sept. 15. It remains in place through Sept. 20.
Dreamforce dates and arrival information
Salesforce says Dreamforce 2026 runs Tuesday, Sept. 15 through Thursday, Sept. 17 at Moscone Center.
Badge pickup starts Monday, Sept. 14 at Moscone West, so visitor traffic will begin increasing before the first conference morning.
Salesforce says Dreampark opens to badge holders at 7 a.m. Sept. 15. Attendees are subject to security screening and must carry government-issued photo identification when collecting badges.
For residents and commuters who are not attending, however, the date that matters first is not Sept. 15. It is Sept. 4–5, when the street network begins changing.
