Napa Earthquake Aftershocks Reveal Additional Roadway Damage

Following the 6.0-magnitude earthquake near Napa, CHP officers say they visually inspected roadways and bridges and found the following locations suffered some roadway damage:

  • State Route 29 Southbound at the George Butler Bridge in Napa. This part of the road is reduced to one lane for emergency roadway repairs until 6 p.m. The speed limit in the area is reduced to 25 mph. Northbound lanes are unaffected. An alternate route is State Route 121, or Imola Avenue, to State Route 221.

The CHP warns drivers to expect significant traffic delays in the affected areas, and avoid them if possible.

All other bridges and major thoroughfares have been visually inspected officers and no damage was noted, according to a CHP statement. Detailed inspections will continue to be performed by Caltrans engineers.
