The overall SR-4 Operational Improvements project consists of several packages of improvements in both directions in the project limits. Each alternative consists of packages with logical termini and independent utility so each package can move forward as an independent project, including the environmental clearance. This also allows the implementation of a combination of packages from different alternatives to maximize benefits with available funding. CCTA would select which packages to move forward to PA&ED based on available funding. For this procurement, CCTA is seeking proposals for the SR-4 Operational Improvements Project – Westbound Phase 1 (Project) for Project Approval and Environmental Document (PA&ED) services. The Project limits are between Willow Pass Road Interchange and the Port Chicago Highway Interchange on WB SR-4, noted as Packages E and F in the PSR-PDS.
