Caltrans crews are preparing for a full closure of the northbound lanes of Interstate 680 in the East Bay this weekend.
The full closure, which will span 55 hours between late Friday evening and early Monday morning, is scheduled between Koopman Road in Sunol and Sunol Boulevard in Pleasanton. During the closure, Caltrans will work around the clock to remove and replace entire sections of the freeway, including repaving.
The work is part of a major reconstruction project for that section of northbound I-680 to enhance safety and provide a smoother ride for motorists. Parts of the roadway have major cracks and have fallen into disrepair.
The section of the freeway was opened in the mid-1960s between the Interstate 580 interchange in Pleasanton and the Mission Boulevard-Highway 238 exit in Fremont, and portions of the road still have original pavement.
The closure begins at 10 p.m. Friday and continues through 5 a.m. Monday.
The southbound lanes of I-680 will not be affected.
