November 2021

The City of Los Angeles Bureau of Engineering's planned two-weekend, full freeway closure, originally scheduled for 41 hours, ended hours early on both weekends (October 22-24 and November 5-7), as workers safely completed falsework removal under the 101 Freeway.

The closure affected a 2.5-mile section of the 101 Freeway, from the 10/101 split to the 5/10/101 interchange just east of downtown Los Angeles.

The falsework removal is an exciting milestone in the ongoing construction of the $588 million Sixth Street Viaduct Replacement Project, scheduled to be completed Summer of 2022. Upon completion of the falsework removal, the underside of the bridge was revealed showing clean lines of concrete. The arches — poured during the May 2021 highway closure — and the bridge deck are now completely freestanding as the cables provide structural support for the bridge.


About the Project

Stay Involved!

The City of Los Angeles Bureau of Engineering is leading the construction of the new, $588 million Sixth Street Viaduct Replacement Project, the largest bridge project in the history of Los Angeles. The completed structure will be a 3,500-foot long viaduct connecting Boyle Heights and the Arts District across the Los Angeles River. The original viaduct was built in 1932, but had significantly deteriorated due to "concrete cancer"; it was demolished in 2016. The new viaduct will have ten pairs of lit arches, bike lanes and wider sidewalks, along with stairway access and bike ramps connecting to 12 acres of recreational and open space under the bridge, including the Len Hill Plaza. The bridge is funded primarily through the Federal Highway Administration, with additional City support. The viaduct will be completed in Summer 2022.
