Cache Creek Rehabilitation Project

The California Department of Transportation (Caltrans) is proposing the Cache Creek Rehabilitation Project on State Route 16 in Yolo County, spanning approximately 5.4 miles from Post Mile 15.1 to Post Mile 20.5. This Resurfacing, Restoration and Rehabilitation (3R) project aims to improve roadway safety and pavement conditions through full depth reclamation of the road surface, where base materials will be recycled and reused on-site. Key physical improvements include widening shoulders to 8 feet, replacing and widening existing bridges with upgraded railings, installing nonstandard roadside signs, and replacing guardrails and end terminals to comply with the Manual for Assessing Safety Hardware (MASH). The project will also implement Complete Street features, such as signs and signals, where feasible. The project is subject to strict environmental and regulatory compliance, including the Title VI Non-Discrimination Policy, the Americans with Disabilities Act, and Caltrans Standard Specifications for air quality and dust control. Construction site best management practices must adhere to the Caltrans Storm Water Quality Handbooks, and temporary high visibility fencing is required to protect vegetation and tree root systems. The project is managed by Caltrans District 3, with key personnel including Project Manager Cameron Haymore and Project Engineer Diego Conejo Gallegos. Environmental review was conducted via a Mitigated Negative Declaration, with a public comment period concluding on September 21, 2026.
