Ocean Beach's biggest recent change wasn't to the sand. It was to the road running alongside it.

What actually closed. In March 2025, the stretch of the Great Highway between Lincoln Boulevard and Sloat Boulevard — the road that had run along Ocean Beach's inland edge for decades — was permanently closed to cars. The closure followed the passage of Proposition K, a San Francisco ballot measure. As part of the changeover, the city moved roughly 40,000 cubic yards of sand from the north side of the beach to the south side. The resulting park, built on the old roadbed, was named Sunset Dunes, and it officially opened to the public on April 12, 2025.

The park was popular immediately. On opening day, 13,000 people showed up to walk, bike, and skate a stretch of pavement that had carried car traffic a few weeks earlier. A dedicated skateboarding area within the park opened that June. For a project that had been fought over for years before it happened, that turnout sent a clear signal: whatever the arguments against closing the highway, a large number of people wanted to use the space once it existed as a park instead of a road.

The politics did not follow the popularity. Joel Engardio, the San Francisco district supervisor who had championed the highway closure and Sunset Dunes, was recalled from office in September 2025, in what reporting on the episode described as a direct reaction to his support for the project. The timing is the whole story here: a park that thirteen thousand people showed up to enjoy on its very first day still was not enough to save the political career of the person who had fought hardest to build it. Popularity and political survival turned out to be two different currencies, and Engardio spent the wrong one.

Opponents kept fighting after the recall. A lawsuit sought to undo Proposition K entirely and reopen the Great Highway to car traffic. In January 2026, San Francisco Superior Court Judge Jeffrey Ross rejected that lawsuit, leaving the closure and Sunset Dunes in place. So the park survived its legal challenge even after its single most visible political champion did not survive his recall — the policy outlasted the politician who built his career on it.

The economic verdict is still unsettled. As of March 2026, businesses along the former Great Highway corridor were reporting inconsistent results: some told reporters their sales had increased since the park opened, while others described the change as minor or negligible. There is no single, settled answer yet on whether Sunset Dunes has been good or bad for the businesses along its edge — only a scatter of individual experiences that have not converged into a clear pattern one way or the other.

The timing wasn't a coincidence. Sunset Dunes sits on top of the same shifting, eroding sand that has forced the city into a much larger, separate fight over a proposed seawall at the beach's south end, meant to protect a wastewater treatment plant from the ocean. That fight — over the sand itself rather than the road above it — was already underway before the highway closed, and it is still unresolved; it is covered on its own in the environment deep dive linked from this page, because it is a genuinely different argument with its own timeline and its own unanswered questions.

Why this matters beyond San Francisco. Sunset Dunes is a case study in a fight playing out in coastal cities everywhere: a road built for cars, running along an eroding, high-value shoreline, that a city decides to hand back to people instead. Nearly every version of that fight has the same three pressure points — an organized, vocal opposition that valued the road as it was; a public that shows up once given something better than a road, whether or not that same public organized to build it; and an economic verdict that arrives slower and messier than the political one. San Francisco's version compressed all three into about six months: the highway closed in March 2025, the park opened weeks later to strong turnout, and by September its most prominent backer had lost his job over it. Whether that trade — a popular public space for a politician's career — looks worth it a few years from now depends on facts nobody has yet: whether the mixed business results settle into a clear pattern, whether the recall changes how the next supervisor handles a similar fight, and whether the sand under Sunset Dunes behaves any better than the sand under the highway did. For now, what is verifiable is only this: the road is gone, the park is open, the lawsuit to reverse it failed, and the man who pushed hardest for all of it is out of office.
