AI Summary
RFP for environmental and engineering services for SR-4 Operational Improvements Project Westbound Phase 1 in Contra Costa County, CA. Services include project approval and environmental documentation to improve traffic flow and reduce congestion.
SR-4 is a major freeway which connects the communities in East Contra Costa County to the San Francisco Bay Area. The segment between the SR-4/Interstate 680 (I-680) Interchange and the Bailey Road Interchange experiences significant directional peak period traffic congestion that is expected to deteriorate in the future. The westbound (WB) direction experiences congestion during the morning commute hours and eastbound (EB) direction experiences congestion during the afternoon commute hours.The overall SR-4 Operational Improvements Project proposes to improve operations along SR4 in both EB and WB directions from 0.3 mile west of the SR-4/State Route 242 (SR-242) separation to the Bailey Road Undercrossing. The project aims to improve traffic operations and travel time in both directions during peak commute periods for all users. The improvements include combination of new auxiliary lanes and conversion of existing auxiliary lanes to general purpose/mixed flow lanes.The Project Study Report – Project Development Support (PSR-PDS) was approved by Caltrans on May 30, 2017. Three build alternative and the “no-build” alternative were evaluated in the PSR-PDS to construct auxiliary lanes and operational improvements along SR4.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.
