From Sonoma County Public Infrastructure. Please be aware that Wohler Bridge will be intermittently closed, as described below. Plan accordingly (and have a backup plan)

Wohler Bridge Project Update🚧

We’re moving forward with the next phase of bridge construction. Upcoming work includes required environmental mitigation and inspections, which may result in partial bridge closures or significant delays in late January or February. Schedules can change, and we’ll share updates as soon as details are confirmed. 

Also Late January or February – Upper Truss Inspection

An additional one to two days of intermittent bridge closures will be required for inspection of the bridge’s upper truss. This work will involve a man-lift positioned on the bridge deck to allow engineers to inspect existing rivets at the top of the structure.

• Traffic will be allowed across the bridge when the lift is not extended.
• Specific dates are still being finalized—more information will be shared as soon as it becomes available.

Road closures are posted here (but this does not include closures in city limits): https://roadclosures-sonomacounty.hub.arcgis.com/
