Contra Costa County, Marin County — Caltrans Toll Region maintenance crews have discovered unsound, spalling deck concrete on the upper deck of the Richmond-San Rafael Bridge (I-580), near Pier #25.
Crews are preparing to close lanes for emergency deck repair. The closure is expected to begin within the hour and may take several hours to complete. The work is likely to impact the afternoon commute.
Lane Closures:
- Westbound (Upper Deck): Lane #2 CLOSED
- Eastbound (Lower Deck): Lane #2 and Lane #3 CLOSED
- Lane #1 will remain OPEN in both directions
Motorists should expect delays and are advised to seek alternate routes or allow extra travel time.
Traffic Control Measures:
Changeable Message Signs (CMS) will alert drivers ahead of closures. At least one lane will remain open in each direction during work hours. Motorists should expect minor delays, reduce speed, and plan extra travel time. Please use caution and be prepared for possible merging traffic near work zones.
