511 Contra Costa

Update: due to rainstorms, the construction of a carpool lane along Eastbound I-80 has been postponed three weeks from the original stated date.

Beginning April 26th, Caltrans will close the ramps between Highway 4 and Eastbound Interstate 80 in Hercules for six months.

Caltrans will shut down access from Highway 4 to Eastbound I-80 at 12:01 am on April 26th; traffic will be rerouted onto local streets. Drivers can use the Cummings Skyway or take Hercules to connect to Eastbound I-80.

The closure is for the addition of 4.7 miles of carpool lane on I-80 between Highway 4 and the Carquinez Bridge, with the intention of easing traffic jams in the long term.

The carpool lane extension will cost about $28.5 million, paid for by funds from the $1 Bay Area bridge toll increase approved by voters in 2004.
