The Bureau of Engineering, under the leadership of City Engineer Gary Lee Moore and in partnership with the City's Bureau of Contract Administration, is leading the Sixth Street Viaduct Replacement Project to replace the original, seismically-deficient structure that was built in 1932. The new $588 million viaduct stretches between Boyle Heights and the Arts District and is the largest bridge project in the history of Los Angeles. It is funded by the Federal Highway Administration and the California Department of Transportation, as well as City funds. Construction is led by contractors Skanska Stacy and Witbeck. The new viaduct is expected to be completed in Summer of 2022.
