Caltrans has begun overnight closures of a portion of U.S. Highway 50 in Sacramento from Interstate Highway 5 to West Sacramento, with a 55-hour full closure set to begin on Halloween weekend, to complete necessary roadwork.

The overnight closures, which began Sunday night, affect westbound Highway 50 from the I-5 interchange to multiple on- and off-ramps in West Sacramento. 

The roadwork is part of Caltrans’s I-80 Pavement Rehabilitation Project, which also includes the portion of Highway 50.

What times will WB Highway 50 be closed in Sacramento and West Sac?

Caltrans said the overnight closures run nightly from 9 p.m. to 4 a.m. through Friday, Oct. 31, from the I-5 and US 50 interchange to west of Jefferson Boulevard in West Sacramento. 

Starting at 10 p.m. on Friday, the closures will last until 4 a.m. Monday, Nov. 3.
