Caltrans will implement overnight lane and ramp closures along Interstate 80, Interstate 980, and Interstate 580 in Contra Costa, Solano, and Alameda counties next week as part of an ongoing fiber optic infrastructure project.
The closures are scheduled from 9 p.m. to 5 a.m. Monday, April 6, through Thursday, April 9.
According to Caltrans, it will affect portions of eastbound and westbound I-80 as crews continue work moving east from McDonald Avenue toward the Carquinez Bridge.
Caltrans said full closures of ramps and lanes are planned at San Pablo Avenue, San Pablo Dam Road, the Hilltop Road on-ramp loop, Richmond Parkway, and Fitzgerald Drive.
Additional nightly closures are also expected near Appian Way, the Carquinez Bridge, the West MacArthur Boulevard connection to I-80 and the I-980/I-580 interchange, transport officials said.
The agency said nightly lane and on- and off-ramp closures along eastbound I-80 between McDonald Avenue and the Carquinez Bridge will continue Sunday through Thursday from 9 p.m. to 5 a.m. through May, weather permitting.
Motorists are advised to follow posted detour routes.
