How will I be affected during the Turning Basin dredging project?

The dredging and docks project will have the following impacts: 

D Street Bridge Closure – Expect Traffic Delays & Detours
The D Street Bridge will be closed to cars, bikes, and pedestrians (all traffic) Monday – Friday, October 3-October 18. The Bridge will be reopened Saturday-Sunday, October 8-9 and October 15-16.

The bridge closure will require all traffic to cross the river at Washington Street.  Trucks will need to detour through Petaluma Blvd. South using the 101 freeway to cross the river while avoiding the downtown.  

Golden Gate and Petaluma Transit will be rerouted during this time to avoid the D Street bridge. For more info on the transit routes, visit 

No Watercraft Access to the Turning Basin During this Project
For safety reasons, access to the Turning Basin will be closed to the public from September 26 through October 18. Boats & personal watercraft – kayaks, paddleboards, canoes, etc. — will not be allowed in the Petaluma River between the D Street Bridge and the Balshaw pedestrian bridge.

No Access to Petaluma Small Craft Center Dock & City Docks (West Side)
The Petaluma Small Craft Center Floathouse and City dock on the West side of the Turning Basin will be removed on October 3, 2022, and reinstalled no later than October 18, 2022.

No Access to East Side City Dock & Gangway
The City  dock and gangway on the East Side of the Turning Basin will be removed on October 3, 2022, and will not be replaced for approximately 13 months, in November 2023. The footpath connecting the City dock to the shoreline along Weller Street (Cavanagh Landing) will be closed during that time.

Dredging can be noisy work. Those who live and/or work adjacent to the Turning Basin should be prepared to hear noise similar to heavy construction work Monday through Friday, 7:00 a.m. to 7:00 p.m. There also might be noise throughout the day as barges travel back and forth from the work site to the disposal site in San Pablo Bay (SF-10).
