Southbound Interstate 680 in the East Bay’s Tri-Valley region fully reopened early Monday morning after a weekend closure for repaving work, Caltrans said.
The partial closure included three left lanes of southbound I-680 between Alcosta Boulevard in San Ramon and the I-580/I-680 connector in Pleasanton. Caltrans said the lanes reopened at 2 a.m. Monday, a couple of hours ahead of schedule.
Two right lanes of southbound I-680 remained open during the project, but traffic through the area still got clogged up. The northbound direction of the freeway remained open.
The same closure is scheduled for May 31 to June 3, and here’s what to know:
