SR-220 Cold Plane and RHMA-G Paving (EA 04-4X970)

The California Department of Transportation plans to perform cold planing and repaving on State Route 220 from SR-84 to the Sacramento County line in Solano County, covering post miles 0.00 to 3.10. The existing pavement will be removed through cold planing and replaced with a 0.10-inch layer of rubberized hot mix asphalt Type G to improve surface quality and durability. Pavement markings and delineation will be updated as necessary to ensure visibility and safety. All roadside signs within the project limits will be replaced using non-ground disturbing installation methods, with wooden posts set in place of the existing signposts to minimize environmental disruption. The project will be executed under one-way traffic control to maintain safety and allow for efficient construction operations. The initiative is identified under the project title SR-220 Cold Plane and RHMA-G Paving (EA 04-4X970) and is forecasted by Caltrans District 4 - Bay Area/Oakland, with the posting date set for June 29, 2026. Primary point of contact for inquiries is Juliane Smith, Senior Environmental Scientist, who can be reached via email or phone for further details regarding environmental compliance and project logistics.
