ELK mountain RD PM 10.75-10.81 stabilize the slip out and embankment. Install a retaining wall to prevent landslide from filling the roadway with SOI

The Federal Highway Administration (FHWA) awarded a $400,000 Project Grant to the California Department of Transportation (Caltrans) on June 23, 2025, under the Highway Planning and Construction program (CFDA 20.205). This award funds stabilization and safety improvements on Elk Mountain Road, specifically at post-mile markers 10.75–10.81 in California. The project will address an active slip-out and embankment failure by installing a retaining wall to prevent landslide material from obstructing the roadway. Upon completion of stabilization work, the project will restore the paved roadway surface to its original grade and width.

This Project Grant represents a targeted infrastructure investment in roadway preservation and safety under the federal Highway Planning and Construction program, which provides financial assistance to state departments of transportation for highway construction, rehabilitation, and safety enhancements. The Elk Mountain Road project addresses critical infrastructure resilience by mitigating geotechnical hazards that pose risks to roadway functionality and public safety.
