The 101 freeway through downtown LA will be closed for 24 hours starting at 10 p.m.

A 2½-mile portion of the 101 freeway through downtown Los Angeles will be closed for 24 hours Saturday night through Sunday night for roadwork.

The closure of the 101 between the Interstate 10 and Interstate 60 interchange is scheduled to begin at 10 p.m. Saturday and last until 10 p.m. Sunday, the city’s Bureau of Engineering said in a news release.

The closure is to allow for median restoration and reconstruction of the road leading to the freeway under the 6th Street Overpass, according to the release. The California Department of Transportation will also perform slab replacement work, officials said.

Drivers traveling north on Interstate 5 from the Orange County area, or west on 60 from the Pomona area, to the 5/10/101 interchange east of downtown city ​​of Los Angeles, are advised to take the 710 freeway north to the 10 westbound, or the 10 freeway to the 110 northbound.

Drivers traveling south on the 101 from the San Fernando Valley area to the 10/101 divide are advised to take the 110 freeway southbound to the 10 eastbound, or the 10 eastbound to Highway 710 southbound.

A map of closure and detour routes is displayed in line.

The 6th Street Viaduct is being rebuilt to replace the original structure, which was built in 1932 and is seismically deficient, authorities said. The new $588 million bridge will connect the downtown arts district and historic Boyle Heights. It is expected to be completed this summer, according to the release.
