After weekend delays, Caltrans announced that it will open an expanded carpool lane on southbound Interstate 680 in Alamo in time for the Thursday morning commute.
The expanded lane will be nearly one mile long and run between Rudgear Road in Walnut Creek to Livorna Road in Alamo. The $1.9 million carpool lane was designed to "encourage carpooling in the corridor by allowing carpoolers to bypass congested mixed flow lanes," according to a release.
Crews will grind bumps in the roadway and repave it before opening, said Caltrans Public Information Officer Allyn Amsk. When the southbound extension is opened, the entire southbound HOV lane will be approximately 13 miles long.
Part of a larger, $49.8 million I-680 rehabilitation project, the carpool extension was paid for with funds from the Measure J transportation sales tax in Contra Costa County.
