The 6th Street Viaduct Bridge in Los Angeles—the site of numerous Hollywood movie scenes—has reached the end of its career. Los Angeles city engineers are internally reviewing the Request for Proposals document for a final design to replace the structure, which consists of two prestressed concrete viaducts and a double steel arch center span, with a cable-stayed structure.
The Los Angeles City Council voted late last year to replace the 3,500-ft-long, 46-ft-wide viaduct in Boyle Heights, just east of downtown. The viaduct extends east-west across the Los Angeles River, Union Pacific Railroad and Metrolink tracks, US 101, and several local streets. Listed on the California Register of Historic Resources, the bridge’s concrete components have the equivalent of cancer.
