SAN RAMON — A weekend-long partial closure of a portion of I-680 in San Ramon began Friday evening to allow crews to repave deteriorating sections of the highway, the California Department of Transportation announced.
Two of four southbound lanes will be closed starting from Alcosta Boulevard in San Ramon to the I-580/I-680 Connector in Pleasanton through 4 a.m. Monday, Oct. 7. The connector will remain open and unaffected by construction. Two right lanes will be open to traffic but Caltrans recommends motorists take alternate routes to alleviate traffic congestion in San Ramon and Dublin.
In addition, a I-680 express lane and left shoulder will be closed heading northbound between Amador Valley Boulevard in Dublin and Alcosta Boulevard.
“Though lanes will be open, it’s best to avoid the area if possible. If you do access the freeway, please be aware of construction vehicles entering and exiting the construction zone and slow for the Cone Zone,” read the Caltrans closure announcement. “Caltrans is aware that the closures will impact the motoring public and measures are being taken to minimize inconvenience.”
The weekend closure will allow crews to repave a deteriorating section of the road, improving safety and reducing the number of night closures needed to complete the project. A weekend closure is equivalent to about 40 days of night closures, Caltrans said. An additional partial closure of this section of I-680 is scheduled for the weekend of Oct. 18 through Oct. 21.
