I-680 Express Lane Completion Project

Project Home Page

The California Department of Transportation (Caltrans), in partnership with the Contra Costa Transportation Authority (CCTA), proposes the Interstate 680 (I-680) Northbound Express Lane Completion Project to improve corridor-wide congestion, travel delays, and operational challenges. The proposed project would construct a northbound express lane from Livorna Road to State Route 242 (SR-242) and convert the existing northbound High Occupancy Vehicle (HOV) Lane from SR-242 to north of Arthur Road near Martinez to an express lane – which means both HOV and single-occupancy drivers who pay a toll can use the lane.

The Draft Environmental Impact Report (EIR)/Environmental Assessment (EA) is currently available for public review and comment. The comment period is from May 8, 2024 to June 24, 2024. Please visit the link above for more details.
