The State Route (SR) 160/Highway 4 interchange included only two of four possible interchange movements: the eastbound Highway 4 to northbound SR 160 connector ramp and the south­bound SR 160 to westbound Highway 4 connector ramp. The SR 160/Highway 4 Direct Connector Ramps project was undertaken to construct two new connector ramps, one connecting west­bound Highway 4 to northbound SR 160, and one connecting southbound SR 160 to eastbound Highway 4. The project included add­ing an additional 12-foot auxiliary lane to the outside of existing SR 160 in both directions between the SR 160/High­way 4 Interchange and the East 18th/ Main Street Interchange, as well as building a sound wall extension and re­taining walls. The southbound SR 160/ Highway 4 separation structure will ac­commodate a future BART extension in the median of Highway 4. The $50 mil­lion project was funded through bridge tolls and completed on time and nearly $700,000 under budget.

CME developed and maintained a detailed financial plan and the Project Management Plan (scope, costs, schedule, risks) and led efforts to close out the project with the Contractor and Cal­trans. CME also attended meetings as CCTA’s representative and oversaw and directed the work of the construction management consultant to ensure compliance of the contractor with certi­fications and licenses, materials certification and testing, labor compliance, and other contract requirements.
