Iconic Sixth Street Viaduct Replacement Project

The Sixth Street Viaduct Replacement Project is the largest bridge project in the history of Los Angeles and is being led by the City of Los Angeles Bureau of Engineering. When complete, the new signature bridge will serve as a unique addition to LA’s skyline and the Los Angeles River as it improves mobility, enhances safety and connects communities.

One of America’s most famous and iconic bridges, the Sixth Street Viaduct, acts as a vital connection between the growing Arts District on the west side of the Los Angeles River and the historic neighbourhood of Boyle Heights on the east side.

Traversed unknowingly by millions of visitors to Los Angeles over the year, the bridge, built in 1932, spans nearly 3,500 feet across the river and has been used to represent Los Angeles’s more gritty side in countless movies, music videos and TV commercials, including riverbed car chases. Probably the most famous being in the Hollywood film, ‘Grease’.

Yet, due to a rare chemical reaction in the cement supports and seismic vulnerability, the Sixth Street Viaduct work is now in progress to demolish and replace the bridge.

Work continues on the massive project, including viaduct demolition, and the start of bridge foundation work in the coming months.

An estimated 48,000 cubic yards of concrete, 1,245 tons of structural steel and 4,200 tons of rebar will be hauled away as construction begins on the replacement viaduct.

In the most recent construction milestone, the initial 220-foot section of the viaduct above the 101 Freeway was successfully demolished in early February 2016.

Advance planning by the City of Los Angeles Bureau of Engineering and Caltrans ensured drivers were aware of closures and alternate routes, minimizing the impact of the 40-hour closure of two miles of the 101 Freeway.
