Yol-16 Vision Zero Shoulder Widening

The California Department of Transportation District 3 is implementing the Yol-16 Vision Zero Shoulder Widening project to enhance safety on State Route 16 in Yolo County, specifically from post miles 21.2 to 21.9. The scope of work includes the installation of 4-foot shoulders on both sides of the highway, which will tie into existing 8-foot shoulders at the northern project limits. Additional technical improvements involve roadway alignment and superelevation adjustments, drainage work at various locations, and the application of cold plane and overlay to the existing asphalt of the traveled way. Safety enhancements also include the installation of rumble strips, the replacement of all existing signs with retroreflective sheeting, and the addition of two new speed limit signs. This project, categorized under NAICS code 237310, has undergone environmental review via an Initial Study with a Proposed Negative Declaration, with a public review period scheduled from September 1, 2026, to September 30, 2026. The environmental assessment indicates that the project will have no significant impacts requiring mitigation.
