Los Angeles, CA - July 08: After more than six years of construction, Los Angeles officials light the 20 arches dubbed the “Ribbon of Light” on the new 6th Street Viaduct during a ceremony at dusk that begins a three-day community celebration to mark its completion, connecting Boyle Heights and the downtown Arts District and replaces one of the city’s structural landmarks.

The four-lane bridge will connect Boyle Heights and the Arts District across a 3,060 foot-breadth that spans the Los Angeles River, 101 Freeway, railroad tracks and Metrolink tracks. Dubbed the “Ribbon of Light,” the $588-million project is considered the most extensive bridge project in the city’s history and took six years to complete, with delays due to COVID-19. The event featured a formal ribbon-cutting ceremony at which city officials held a news briefing from L.A. Mayor Eric Garcetti, Councilman De Leon and city engineer Gary Lee Moore. The new viaduct’s “Ribbon of Light” design, with its 20 arches, was created by the architectural firm HNTB Corp. and Los Angeles-based architect Michael Maltzan. (Allen J.
