Notice of limitation on claims for judicial review.

The FHWA, on behalf of the California Department of Transportation (Caltrans), is issuing this notice to announce actions taken by Caltrans that are final agency actions. These actions relate to the proposed Interstate 680 Northbound Express Lane Completion Project in Contra Costa County, California. Caltrans, in partnership with the Contra Costa Transportation Authority, is proposing to construct an express lane on northbound Interstate 680 from Livorna Road to State Route 242, with a 2-mile gap in the express lane at the State Route 24 Interchange in Walnut Creek; construct braided ramps at Treat Boulevard; and convert an existing high-occupancy vehicle lane from State Route 242 to north of Arthur Road to an express lane.
