Son 12 Closure Rescheduled



Lane Closures on State Route 12 east of Santa Rosa will Shift to Nighttime Work

Daytime traffic control for gas line replacement in the Oakmont neighborhood will be shifted to PM to reduce congestion


Caltrans has revised a permit for work crews to replace a gas line on State Route 12 in Sonoma County, shifting the one-way traffic control hours from daytime to nighttime to reduce traffic backups.

The permit had authorized lane closures between 9:30 AM – 3:00 PM. Now permitted hours are 9:00 PM – 6:00 AM.  

Caltrans canceled daytime traffic control on Friday, December 10, 2021. Work will begin again on Sunday night, December 12, 2021. 

Route 12 PGE


After crews replace the gas line, which should take at least several nights, not including delays caused by rainy weather, the area will be repaved. 


At that point, daytime closures may reoccur for several days because ambient temperatures will likely be too cold for paving. Asphalt will not adhere at temperatures below 50-degrees Fahrenheit.
