I-10 Ramp Metering and Widening Caltrans EA 38434

This project will widen eleven entrance ramps and install metering devices to improve traffic flow and relieve congestion on Interstate 10 (I-10) between Cedar Avenue and Interstate 215. This $10 million project will incorporate state of the art technology in detecting traffic flow on the freeway mainline and determine when ramp meters should be activated.  This will be an important operational improvement to I-10 motorists and will help relieve congestion during daily peak periods as well as off peak periods when there is congestion due to unexpected events such as accidents or lane closures.

The project required close coordination between several departments within District 8, including Design, Traffic Design, Electrical Design and Landscape Architecture to make sure all features of the project were coordinated properly.  This project also utilized Proposition 1B funds, which put strict deadlines on project delivery, which was achieved as originally scheduled.

The Southtstar project manager worked closely with all District 8 functional units to deliver the PA/ED, PS&E and Right of Way phases on-time and within the support budgets programmed for the project. This enabled the project to move to construction when funds became available.
