No on Proposition G

Allowing Private Vehicles on the Great Highway in Sunset Dunes Park

What is it?

Prop G would close Sunset Dunes Park and reopen the Upper Great Highway to cars for most of the week. It restores a version of the weekend compromise that ran from 2022 to 2024: the road will be closed to private vehicles from Friday at 6:00 p.m. through Monday at 4:00 a.m., and on holidays.

Reopening the road to cars would require a coastal development permit from the California Coastal Commission, and possibly other approvals.

Why vote No?

San Francisco has voted on this twice. In 2022, we rejected a measure to keep cars on the Great Highway, 65% to 35%. In 2024, we passed Prop K and built Sunset Dunes. The park is a hit: 1.7 million visits in its first year, more than half of them on weekdays (the very days Prop G would give back to cars).

Prop G asks the whole city to vote on the same question a third time, and it would require a fourth election to ever adjust the hours. This is exactly the broken process Prop D fixes: about 10,600 signatures can put any settled question back on your ballot, again and again, forever.

Vote no on Prop G. Let's all move on.
