The SR 99 Feasibility study will address major mobility challenges on a 12 mile segment of the SR 99 corridor between the 5/99 Interchange in Sacramento County and the 70/99 split in Sutter County. This segment was identified in the Corridor System Management Plan as a priority for potential improvements. The study will attempt to identify and prioritize corridor improvements, including the addition of HOV lanes, mixed flow lanes, auxiliary/transition lanes, and ramp metering that will improve mobility along the corridor over the next 25 years.To view the project area and proposed improvements, please view the videos and map below.
