Site work and new construction of a road / highway in Petaluma, California. Design plans call for the construction of a road / highway.

The city of Petaluma has $23 million set aside in a fund to build the first phase of the Rainier crosstown connector and interchange and the first segment of the project could be under construction as soon as 2019. Voters approved the construction in 2004 and since that time, the city has spent millions of dollars on design and environmental studies to ensure that the Rainier Avenue extension project's first phase, an undercrossing, is completed when Highway 101 is widened through Petaluma. In July, the city council authorized the City Manager to negotiate for the acquisition of property off Petaluma Boulevard North, the future western terminus of the .65-mile Rainier Avenue extension. The connecting roadway passing under the freeway and over the railroad tracks and the Petaluma River will comprise the first phase of the project's completion. Phase two, a freeway interchange, will need the California Department of Transportation's approval. The end result of the project will be to link Petaluma Boulevard North with the intersection of Rainier Avenue and McDowell Boulevard. As of May 26, 2022, this project is currently in the planning and initial design phase.. This project is not fully funded and a project timeline has not been confirmed. The city is working on property acquisition to acquire the property before moving into the final design phase. *Project information, including timeline and contacts, has been obtained through public sources.
