D Street Bridge to Temporarily Close for River Dredging

Posted on October 1, 2020

What: Closure of D Street Bridge to all traffic

When: Continuously from 12 pm (noon) on Sunday, October 4 to the end of the day Tuesday, October 13


Starting Sunday, October 4 at 12 pm (noon) through the end of the day Tuesday, October 13, the D Street Bridge will be closed to cars, bikes, and pedestrians to accommodate the current river dredging project. This street 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.  Go to cityofpetaluma.org/riverdredging/ to see the detour map.

The dredging is scheduled to be completed by mid-October.  Once complete, boats will be able to navigate up to the turning basin, bringing tourism and business to Petaluma.

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

The dredging of the Petaluma River, which last occurred in 2003, is sponsored by the Army Corp of Engineers.  This work is being done continuously to ensure completion by mid-October.

People living and or working near the river may hear noise from the dredging.  For questions about the project, contact Jonathan Sanglerat at 707-292-2772 or [email protected].
