Road 274(838) remove roadway structural section. Excavate past the slope failure plane. Bench and key slope fill. Replace compromised section of road

The Federal Highway Administration awarded Caltrans (California Department of Transportation) a Project Grant totaling $596,050 on June 20, 2025, under the Highway Planning and Construction program (CFDA 20.205) to address critical roadway infrastructure failure on Road 274(838). The project delivers comprehensive remediation services including removal and replacement of the compromised roadway structural section, excavation beyond the slope failure plane to ensure structural stability, benching and keying of slope fill to prevent future failure, and hydroseeding of the slope fill to control erosion and stabilize the repair area. This repair work addresses a localized but significant infrastructure deficiency requiring specialized excavation and fill work to restore full roadway functionality and safety.

As a state transportation agency administering federal highway funds, Caltrans executed this project-specific award in California consistent with the Highway Planning and Construction program's framework for state-administered highway preservation and improvement activities. The project scope reflects standard highway maintenance and safety protocols under federal-aid highway funding mechanisms, which authorize both formula and discretionary allocations to states for construction, preservation, and improvement of eligible highway infrastructure.
