Construction Milestones Coming in 2019 |
|---|
The Bureau of Engineering's Sixth Street Viaduct Replacement Project continues into 2019 with many construction milestones ahead of us. Construction, as you may have seen driving or walking by the site, is moving from east to west, which means new phases of construction start over or next to the 101 Freeway in Boyle Heights and moves toward the Arts District.
The most exciting thing in the new year is that Los Angeles to see the upper parts of the bridge come to life in the coming year. Here are just some of the things to look for in the coming year:
Arch Rib Floor Beams
Floor beams span the width of the bridge and connect each pair of Y-Bent supports. This is the first phase of building the deck, which is the floor of the bridge that cars drive on. Crews will install falsework to create the shape of the floor beams, rebar will be laid for reinforcement, and then concrete will be poured to create the finished portion. The arch ribs are shaded blue in the diagram.
Bridge Deck
Once we have the arch ribs poured, we can start the deck of the bridge, which will really show the viaduct taking shape as we can begin to see where the roads and walkways will be placed. The deck is shaded pink in the diagram.
 Arches
The 10 pairs of arches are one of the most iconic and exciting elements of the new viaduct. Once we start pouring concrete for the arches people will begin to see what the final viaduct will look like. The arches are in brown.
Arch Cabling The arches will have criss-crossing heavy cables that provide support to the entire bridge.
These are just some of the construction phases to look for in the new year! We'll continue to share updates as they happen.

The Sixth Street Viaduct Replacement Project is a new, 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 $482 million dollar project is the largest bridge project in the history of the city. The bridge is funded primarily through the Federal Highway Administration, with additional City support. The viaduct is expected to be completed by the end of 2020. |
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.
