The illuminated glass block and white concrete ribbon runs for 2.5 miles along San Francisco’s waterfront, centered on the refurbished Ferry Building. The project’s concept was to demarcate the actual edge of San Francisco as it reaches its primary seawall and abuts the bay. Beyond the seawall the city stands on piers. The Art Ribbon traces the city’s real edge hidden below. The installation serves as a public amenity, integrating street furniture, sidewalk, and public art. Collaboration: Stanley Saitowitz and Vito Acconci.
