A new express lane on southbound Interstate 680 opened to traffic Friday along 9 miles between Alameda and Contra Costa counties.
The new express lane runs from Alcosta Boulevard south to state Highway 84, and won’t have tolls charged until more work on the project is completed later this year, according to the Alameda County Transportation Commission, which serves as the county’s traffic congestion management agency.
Construction on the project began in 2023 and was funded through a combination of local, regional and state sources, including a sales tax in Alameda County.
Another express lane will be installed on the northbound side of the same stretch of highway, though the construction will take place at a date yet to be determined, according to the county commission.
“This new segment will provide smoother, more predictable trips for drivers every day, strengthening a regional corridor while improving the quality of life for people who travel here each day to get to work and return home to their families,” commission chair and Alameda County Board of Supervisors president David Haubert said in a statement.
More information about the project can be found on the Alameda County Transportation Commission website.
