Specifications include, but are not limited to: The County, in conjunction with the California Department of Transportation (Caltrans) and the Federal Highway Administration (FHWA), is proposing the replacement of the four (4) existing structurally deficient bridges over branches of Howard Slough, each of which was individually programmed in the Highway bridge Program. The existing bridges are single-lane reinforced concrete slab bridges varying in length 40’ to 500’ and are located on a 0.75-mile segment of County Road 67 between County Road Z and Glenn/Butte County Line, approximately 17 miles southeast of the City of Willows. The replacement structures will be two-lane multi span continuous cast-in-place concrete slab bridges. The entire 0.75- segment of County Road 67 will be reconstructed. The existing County Road 67 alignment will be used for access to the Project. The total area of potential effect (APE) of the Project, is approximately 12.14 acre, see attachment D.
