Successful Freeway Closure
Leads to Safe Arch Pour Over 101 Freeway

The City of Los Angeles Bureau of Engineering's planned full freeway closure last month, originally scheduled for 55 hours, ended hours early, as workers safely completed two more arches over 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. When Engineering completed work on the arches overheard, the California Department of Transportation's District 7 crews stepped in to do much needed freeway maintenance work, including weed and graffiti removal, guard rail and sign repairs, pavement repairs and pothole filling.

The arch work is part of the ongoing construction of the $588 million Sixth Street Viaduct Replacement Project, scheduled to be completed Summer of 2022.

Followers of Bureau of Engineering's social media watched along as workers scaled the arches and poured concrete into the two arches.

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. The bridge is funded primarily through the Federal Highway Administration, with additional City support. The viaduct will be completed in Summer 2022.
