A portion of Interstate 680 is shut down for this weekend to allow crews to continue a paving project in the East Bay.
The partial closure includes three left lanes of southbound I-680 between Alcosta Boulevard in San Ramon and the I-580/I-680 connector in Pleasanton. Caltrans said lanes were shut down at 9 p.m. Friday and it will remain closed through 4 a.m. Monday.
Two right lanes of I-680 will remain open during the project, but Caltrans encourages motorists to take alternative routes.
"This is an area that even if there aren’t any closures at all it gets pretty congested, especially on the weekends," Caltrans spokesperson Janis Mara said. "We are doing our best to accommodate folks by having those two lanes open, but if at all possible we do ask the motoring public to avoid the area if you can."
The same closure is scheduled for May 31 to June 3.
