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.
