A full weekend closure of southbound Interstate 680 (I-680), between Alcosta Boulevard in San Ramon and the I-580/I-680 connector in Pleasanton, will take place Friday, September 20, through Monday morning, September 23. The Saint Patrick Way on-ramp onto southbound I-680 will also be closed.
Southbound I-680 will be closed between Alcosta Boulevard in San Ramon and I-580/I-680 connector in Pleasanton, from 9:00 p.m. on Friday, September 20, through 4:00 a.m. on Monday morning, September 23. However, all I-580/I-680 connectors will remain open through the right-most lanes on southbound I-680. Motorists are encouraged to take alternate routes to alleviate traffic congestion within the construction work zone on southbound I-680 in the cities of San Ramon and Dublin.
In addition to full closures on southbound I-680, the far-left lane (Express Lane) and left shoulder will be closed on northbound I-680 between Amador Valley Boulevard in Dublin and Alcosta Boulevardin San Ramon. During the closure, the contractor will replace a portion of the existing deteriorated roadway with new pavement on southbound I-680, from Alcosta Boulevard to I-580/I-680 connector.
The work will repair deteriorating existing pavement and enhance motorist safety while reducing the number of nightly closures needed on the project. This weekend closure is expected to accomplish the amount of work that otherwise would require an estimated 40 nighttime closures.
After this full closure, there will be two additional partial weekend closures of southbound I-680, allowing motorists to travel on southbound I-680 through the construction work zone. The dates for these additional partial weekend closures are scheduled for October 4 - 7, and October 18 - 21, 2024.
In the case of rain or unanticipated developments, the closures will be rescheduled, and the public will be notified.
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.
The northbound I-680 and I-580/I-680 interchange connector will remain open and will not be affected by the closure.
