Overview
- San Francisco’s Department of Elections certified on Thursday, July 23, 2026, that a citizen petition has enough valid signatures to put a measure on the November ballot to reopen the Upper Great Highway to cars on weekdays.
- The measure would restore weekday vehicle access while keeping the roadway a park on weekends in the arrangement backers call a “compromise.”
- City agencies and advocates offer sharply different cost estimates for reversing Sunset Dunes, with Rec and Parks and SFMTA staff emails citing about $10.75 million and other city analyses citing more than $14 million and warnings that total costs could approach $20 million.
- Sunset Dunes has drawn heavy use since it opened in April 2025, recording more than 1.7 million visits overall and roughly 525,000 visits from January to March 2026, with park supporters saying weekdays account for a large share of use.
- The campaign will be highly political because the dispute has driven recalls and close elections on the west side, with a broad coalition of supervisors and state Sen. Scott Wiener opposing the repeal while neighborhood leaders and measure backers argue weekday car access is needed to ease local circulation.
