Built in 1932, the two-thirds-mile-long Sixth Street Viaduct is the last-built and grandest of the monumental river bridges, with its graceful steel arches and Classical Moderne design.

The bridge stands as an iconic gateway to both sides of the Los Angeles River and was determined eligible for listing in the National Register of Historic Places in 1986. Featured in countless films, television shows, and commercials, it is the most widely recognized of the historic river bridges.

In 2008, the bridge was designated as Los Angeles Historic-Cultural Monument #905.

The bridge closed on January 27, 2016 to prepare for demolition. Unfortunately, the bridge cannot be saved due to the alkali-silica reaction (ASR) that is slowly destroying it and making it unsafe. Learn more on our issue page.
