SAN RAMON – A partial closure of a portion of I-680 in San Ramon began Friday evening over the weekend to permit emergency crews to repair damaged sections of the highway, the California Department of Transportation said.
Two of 4 southbound lanes shall be closed from Alcosta Boulevard in San Ramon to the I-580/I-680 interchange in Pleasanton until 4 a.m. Monday, Oct. 7. The connection stays open and isn’t affected by the development work. Two right lanes shall be opened to traffic, but Caltrans is recommending motorists take alternate routes to ease traffic congestion in San Ramon and Dublin.
Additionally, an expressway and the left shoulder of northbound I-680 shall be closed between Amador Valley Boulevard in Dublin and Alcosta Boulevard.
“Although the lanes will be open, it is best to avoid the area if possible. When entering the highway, please be aware of construction vehicles entering and exiting the construction zone and slow down toward the cone zone,” Caltrans’ closure notice said. “Caltrans recognizes that the closures will impact motorists and is taking steps to minimize inconvenience.”
The weekend closure will allow crews to rehabilitate a deteriorating section of road, increasing safety and reducing the variety of overnight closures required to finish the project. A weekend closure is similar to about 40 days of overnight closures, Caltrans said. Another partial closure of this portion of I-680 is planned for the weekend of October 18-21.
