Caltrans is scheduled to close southbound Interstate 680 in Pleasanton between Sunol Boulevard and Koopman Road on Friday, June 9 through Monday morning, June 12, 2023.

Portable changeable message signs will be placed prior to closure advising motorists of this closure and will remain in effect throughout the weekend while work is being performed.
 
Northbound I-680 will remain open and will not be affected by the closure.
 
Caltrans is aware that the closures will impact the motoring public and measures are being taken to minimize inconvenience. Caltrans thanks the motoring public in advance for your patience as we work to improve I-680.
