$166M federal grant to ease congestion, add express lanes along Interstate 680 corridor

A $166 million federal grant will add lanes to fight congestion on northbound Interstate Highway 680 from Walnut Creek to Martinez, the Contra Costa Transportation Authority said.

The project will build a northbound express lane from Livorna Road to state Highway 242 and turn a high-occupancy vehicle lane into an express lane from Highway 242 to north of Arthur Road, the authority said Friday.
