24-Hour Reverse Traffic Control at Cummings Skyway Overcrossing near I-80 in Crockett

Contra Costa County - Caltrans has installed temporary traffic signals and lane striping to implement 24/7 reverse traffic control. Additionally, during peak hours from 6:30 AM to 6:00 PM, flaggers will assist in directing traffic at the Cummings Skyway Overcrossing in the City of Crockett. Caltrans will also continue guardrail replacement and concrete barrier installation beginning Tuesday, September 24, 2025.

All work is expected to be completed by March 31, 2026, and subject to change, weather and field conditions permitting.
