Interstate 80 Sacramento/Yolo County Ramp Metering Project

Project Facts


This project will widen ramps, install amps meters, California Highway Patrol (CHP) Enforcement and Maintenance Vehicle Pullout areas on Interstate 80 in Sacramento and Yolo Counties at various locations. Ramp metering will help reduce traffic congestion on the freeway system, minimize vehicle delays and reduce traffic accidents. All ramp locations in this project are listed in the Caltrans District 3 Ramp Meter Development Plan 2013 (December 2013).

Project Benefits

Purpose: The purpose of this project is to help relieve traffic congestion on the freeway and reduce vehicle delays.

Need: Several non-metered locations remain in the Sacramento metropolitan and Yolo County area ramp metering system. These locations, where traffic can enter the freeway unregulated, cause increased congestion and freeway queuing. Drivers divert to these locations because they are not metered. Installation of ramp meters and HOV preferential lanes (where it is possible) reduce congestion, improve merging and weaving conditions, and improve safety. Residential and employment growth along these corridors have led to a steady increase in traffic volumes. Congestion-relieving measures, such as ramp metering, are required.
