State Route 9 Post Miles 1.0 and 4.0 Permanent Restoration Project
Caltrans is planning to construct two sidehill viaducts along State Route 9 between the City of Santa Cruz and the community of Felton. The viaducts are proposed at post mile 1.0 just north of Santa Cruz and post mile 4.0 just south of the entrance to Henry Cowell Redwoods State Park. In these areas, landslides caused by heavy rainstorms have damaged the highway. The proposed project would restore the highway and stabilize the overly steep slopes.
Purpose: The purpose of this project is to stabilize the cut slopes and permanently restore State Route 9 to its previous function.
Need: The project is needed because heavy rainstorms in early 2017 caused landslides (slip outs and slope failures) on the slopes above the northbound lanes of State Route 9 at post miles 1.0 and 4.0. Stabilizing the slopes is needed to permanently restore the facility and eliminate impacts to the traveling public.
Estimated Funding Breakdown
The currently programmed construction cost for the project is $13,065,000. Funding would come primarily from the State Highway Operation and Protection Program (SHOPP) under the Major Damage, Permanent Restoration Program. The project is eligible for federal funding.
