Historic Wohler Street Bridge Near Healdsburg To Close For 6 Months

SONOMA COUNTY, CA— As the Wohler Road Bridge seismic retrofit project enters its second and final year of construction, the bridge over the Russian River will close to traffic for over 6 months, it was announced this week.

Closure of the bridge near Healdsburg starts April 1 and ends Oct. 15, county officials said. As the critical safety upgrade is completed, work will include replacing steel elements on the 103-year-old bridge, deck demolition and replacement, and pier footing retrofit.

The Sonoma County Board of Supervisors awarded an $18 million construction contract in February 2024 to Ghilotti Construction Company, Inc. for the seismic retrofit of the historic bridge.

During the upcoming construction, drivers who need access to Wohler Road will be diverted onto Eastside Road, U.S. Highway 101 and Westside Road, then back onto Wohler. Below are some detour maps provided by the county.
