As part of the on-going construction of the Sixth Street Viaduct, the Bureau of Engineering and its construction partners, Skanska-Stacy & Witbeck (SSW), are conducting some partial, overnight closures of the 101 Freeway during the month of March.

The closures started on February 27th and are expected to continue for two weeks. These are overnight closures only, starting at 11:00 p.m. and ending at 5:00 a.m. (Friday work starts at 12 midnight and ends at 6:00 a.m. No work on Saturday nights). Only one direction of the freeway will be closed at a time, starting with the Northbound lanes.

Closures will take place on the eastside of the LA River in Boyle Heights between the North 5 Freeway and North 101 Connector, and the East 60 Freeway and North 101 Freeway Connector to 1^st  Street.

The closures allow for the installation of falsework over the freeway.

Falsework  provides the temporary structural support for the bridge while it is being constructed and allows us to build the Y-Bents, the reinforced concrete structures that will hold up the new bridge. To build the Y-Bents, the pre-fabricated metal falsework forms are assembled and rebar is placed inside. When ready, we will pour concrete into the forms, then remove the forms, which then creates the Y-Bents. Some single lane closures may be required during the concrete pour.

The Y-Bent forms are specialized structures that had to be trucked in all the way from Indiana and Toronto. This is due to the shape of the Y-Bents; they will have gentler curves, as opposed to right angles, and create the distinctive shape of the new viaduct. In total, there will be 18 Y-Bents. Each will come out of its own column, which may extend up to 150 feet underground. As you can see in the photos, it's starting to look like a bridge out there!

Councilmember José Huizar (CD14) and the Bureau of Engineering invite you to attend a community meeting to discuss the Mission & Jesse Roundabout Project. This Active Transportation Program (ATP) project will help reconfigure the intersection of Mission Road, Jesse Street, and Myers Street, a key intersection leading to the Sixth Street Viaduct. 

The meeting will take place on Tuesday, March 13, 2018 at 6:00 p.m. at Boyle Heights Tech Center 1600 E 4th Street. 

 Come provide input on the design of the new roundabout!

If you have any questions, please contact the Boyle Heights Field Office at (323) 526-9332. 

The State of California's Active Transportation Program (ATP) consolidates existing federal and state transportation programs, with the goal of encouraging increased use of active modes of transportation such as biking and walking. 

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.
