A 55-hour closure of the 101 Freeway through downtown LA will take place starting Friday April 30th at 10 p.m.

The closure will allow crews to work on two new arches on the Sixth Street Viaduct, according to a Facebook post by the City of Los Angeles Bureau of Engineering.

“This weekend, watch out for detour signs as Route 101 through Downtown LA will be closed between Friday, April 30 at 10:00 PM and Monday, May 3 at 5:00 AM due to concrete arch construction at the Sixth Street Viaduct Replacement Project!”

The $588 million project, is the largest bridge project in the history of Los Angeles, and it will replace the original, seismically-deficient structure that was built in 1932, according to the Sixth Street Viaduct Replacement Project website.
