Yolo County — Caltrans is alerting motorists about one-way traffic control on State Highway 128 for emergency work.

Wet weather and saturated soil caused an early-morning slip underneath the roadway on Saturday, April 1, resulting in the closure of the eastbound and westbound directions at different locations.

An emergency contractor brought in heavy equipment for slide removal and slop-stabilizing work at postmiles 1.75 and 2.24. One-way traffic control for SR 128 will begin by Saturday afternoon.


  • Postmile 2.24 washout - Temporary sheet piles have been installed, paving, striping, k-rail, and temporary lighting is scheduled for completion Saturday.
  • Postmile 2.22 culvert washout - Currently placing rock slope protection (RSP), scheduled to be fixed later today.
  • Postmile 1.6 landslide – The remaining portion of excavation and RSP/under drain installation is set to be complete today. Rebuilding the shoulder, repaving and restriping is set to be completed Saturday.

A permanent retaining wall project is still in the design phase and will be scheduled at a date to be determined.
