Caltrans will build a retaining wall to bolster the roadbed that was severely eroded on December 18, 2025, when a nearby creek, swollen by several days of rain, washed away much of a slope supporting the highway.

Caltrans estimates that the retaining wall will be complete in September 2025, at which time, the one-way traffic control will be lifted.
