West Spain Street Rehabilitation Project Underway — Weather May Affect Schedule

Posted on November 10, 2025


No parking and construction signs posted along West Spain Street in downtown Sonoma. Orange-and-white barricades with “Tow-Away No Parking – Construction” notices line the sidewalk, with cars parked and businesses visible in the background under a clear blue sky.

The West Spain Street Rehabilitation Project is now underway. The project, managed by the City of Sonoma and constructed by Team Ghilotti, Inc., includes pavement grinding, repair of localized pavement failures, new striping and signage, and utility structure adjustments. Work is taking place along West Spain Street between 1st Street West and 3rd Street West, and from Junipero Serra Drive to Highway 12.

Construction is expected to continue through early December, weather permitting. With rain in the forecast, schedules may change. Residents and motorists are encouraged to stay alert for updated signage and possible traffic impacts throughout the project area.

What to Expect

  • Traffic control will generally be limited to one lane to allow vehicles to pass through the work zone.
  • Short detours and delays are expected, particularly during paving operations between November 11 and November 17.
  • Work hours: Monday through Friday, 8:00 a.m. – 6:00 p.m.
  • Emergency vehicles will have access through the jobsite at all times.
  • Message boards will be placed along the corridor with current information and detour guidance.

Motorists are advised to allow extra travel time and to use caution when driving near crews and equipment. Please avoid entering the work zone until directed by flaggers as driving on freshly placed asphalt can cause serious vehicle damage.

For questions or coordination needs, contact Team Ghilotti’s project representative, Gabe Duran, at (707) 789-7096, or the City of Sonoma at (707) 938-3681.
