Document Description
As a major north-south freeway, I-680 is a heavily traveled corridor that connects the southern San Francisco Bay Area with Interstate 80 (I-80) and passes through Santa Clara, Alameda, Contra Costa and Solano counties. Within Contra Costa County, travelers experience congestion, traf?c bottlenecks within the corridor, and increased travel times. To improve system continuity, congestion relief and operations, the project—part of CCTA’s INNOVATE 680 program—proposes to construct a northbound express lane from Livorna Road to State Route 242 (SR-242). It would also convert the existing northbound high-occupancy vehicle (HOV) lane that runs from SR-242 to the Benicia-Martinez Bridge Toll Plaza, to an express lane. The goal of the project is to complete the I-680 express lane network through Contra Costa County to increase travel speeds for those choosing to use the express lane.
