Petaluma Boulevard South Complete Streets

Wondering what in the world is going on these days on Petaluma Boulevard South? Quite a bit, actually!

Over the next 6 months, Petaluma Boulevard South, the southern gateway to our city (and the original Highway 101), will be getting some major upgrades. Often referred to as a “complete streets” approach, the work being done in this area will benefit all users including pedestrians, bicyclists, and motor vehicles.

The Petaluma Boulevard Complete Streets Road Diet will transform the Boulevard South from Crystal Lane to downtown, providing increased safety, mobility, and access for all road users. The current four lanes of traffic will be reduced to two, making room for bike lanes and improved pedestrian safety. Construction on this phase of the project is anticipated to begin in January 2022.

All work is expected to be completed by the fall of 2022.

Project Updates

The Petaluma Boulevard South Complete streets project is getting close to completion!  Our contractor is currently finishing up curb ramp installations and has begun to lower the metal utility covers in the roadway in preparation for repaving.  Please travel with caution as this work is happening in the travel lanes.  Repaving is scheduled to start on Monday, May 31st, beginning at D Street and continuing south.  Thru traffic and driveway access during the repaving will be provided, but parking along the boulevard will not.  Be aware that orange cones, delineators and temporary lane markings will be used to guide traffic and the configuration will change.  If you have any question or concerns of the upcoming activities, please contact City staff at 707-331-2316.
