Caltrans has started two repair projects in Sonoma — on State Route 12 from Napa Road to the junction with State Route 121, and on State Route 121 near Schellville from State Route 37 to the Sonoma Creek Bridge (near the junction with State Route 116).

This work will continue for the next few months while the contractor repairs the roadway, removes old pavement and repaves. Most of the work will be completed at night, with increased noise as the contractor works through the area.

One lane will be closed on State Route 12 from Napa Road to the State Route 121 junction during work hours of 6 p.m.-8 a.m. weekdays on State Route 12 and 9 p.m.-5 p.m. weekdays on State Route 121.
