The new Sixth Street Viaduct and companion PARC (Park, Arts, River and Connectivity Improvements) are transformative infrastructure projects in the City of Los Angeles. Equal parts architecture and engineering, the new viaduct’s iconic arches span the Los Angeles River, connecting Boyle Heights to the east and Arts District to the west. Designed to accommodate cars, and incorporate significant new bicycle connections, the design also allows pedestrians to access the viaduct above by stairs from the recreational and open spaces below, linking the bridge, the Los Angeles River, and the park in a more meaningful way. Designed by Michael Maltzan Architecture and led by the City of Los Angeles Bureau of Engineering, the viaduct is expected to be completed in 2022.
