Mayor Garcetti Tours Sixth Street Viaduct Site

Last month, Mayor Eric Garcetti toured the Sixth Street Viaduct Replacement Project construction site with City Engineer Gary Lee Moore and Julie Allen, Bureau of Engineering's program manager for the project.

The Mayor walked the site with our staff and checked out the seismic bearings that will allow the bridge to safely shift in the event of an earthquake. He spoke to some of the workers on the project site and also checked out the magnificent views of downtown LA from the east side of the 101 Freeway, where the new bridge will connect to Boyle Heights.

Thank you to the Mayor and his staff -- longtime supporters of the project -- for taking the time to tour the site with us.

Bridge Deck Coming Together with

Transverse Arch Rib Floor Beams

As our crews complete the final Y-Bents on site, we are starting on the Transverse Arch Rib Floor Beams that connect with the Y-Bents. The Bridge Deck will then be installed on top of these horizontal beams. This is the beginning of the parts of the bridge that will be used by cars, bikes and pedestrians.

As you can see in the diagram below, there are multiple components that come together to form each section of the new bridge. We'll keep you posted as we add each section and explain how each section is bring the new viaduct to life. 


About the Project

Stay Involved!

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.
