Segment of freeway being converted into a garden

"The 1989 Loma Prieta earthquake left many of San Francisco's urban freeways structurally unsound. (Back then, there were many, carving up the core of the city.) But the flipside was a boon: The teardown of broad segments of elevated road has led to the revitalization—the reinvention, really—of neighborhoods like Hayes Valley. It has also given the city chunks of unused space where ramps to the old Central Freeway haven't led anywhere in years."
