Happy holidays from all of us at the Bureau of Engineering!
Please take a moment to celebrate with us the amazing progress we've made this past year at the Sixth Street Viaduct Replacement Project. Thank you to everyone on the team who made it possible!
JANUARY
Back in January 2021 we were just starting to build out the falsework for the arches to come.
FEBRUARY
We continued to build falsework for arches.
MARCH
In March we had falsework built on six of the twenty arches and started preparing to pour concrete.
APRIL
April was a very exciting month as we started pouring concrete to make the iconic arches. 
MAY
In May we closed the 101 Freeway for the weekend so we could pour the arches above the freeway.
JUNE
In June we removed the falsework from the first arches, revealing their sleek design!
JULY

AUGUST
By August, with formwork removed from the completed arches, we started on cable embeds, which are used to connect the cables to the edge girders at the bottom of the arch.
SEPTEMBER
In September we started preparing for cabling. Over 15,000 feet of steel cable will be used to support the bridge!
OCTOBER
In October we started hanging cables!
NOVEMBER
November brought another weekend 101 Freeway closure which allowed us to remove the falsework under the viaduct. Once again, we finished early, allowing us to reopen ahead of schedule.
DECEMBER
The bike/pedestrian helical ramp is starting to take shape.
Thank you for being a part of the Sixth Street Viaduct journey. Happy New Year!

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. |
The Bureau of Engineering is the City's lead agency for the planning, design and construction management of the City's public buildings and its public infrastructure. Engineering is also responsible for managing permitting for all construction that takes place in the public right-of-way, as well as managing the City's state-of-the-art online mapping system, NavigateLA. Engineering is committed to designing and building environmentally-sustainable projects that include extensive community input. Engineering projects and services support the City's goals of creating a prosperous, livable and safe city for all residents and businesses.
