Los Angeles is a city defined by infrastructure, characterized by the freedom its freeways originally enabled and symbolized. As the city has become more dense, infrastructure now isolates as much as connects. The Sixth Street Viaduct represents a new model for how multimodal infrastructure can reconnect and revitalize our cities.

The 3,500 foot long viaduct and its lines of twin arches, for which Wil Carson was the Senior Designer and Hiroshi Tokumaru the Senior Technical Coordinator at MMA, links downtown Los Angeles’ nascent Arts District with the history and heritage of Boyle Heights to the east, spanning the L.A. River, which is undergoing a transformation of its own. A large new urban park by Hargreaves Associates spans the spaces adjacent and beneath, with additional links for pedestrians, cyclists, and vehicle connectivity across the entire span of the Viaduct creating a more consequential, reciprocal relationship between this new icon and the surrounding city.
