Rainier Crosstown Connector

Project Description

This project includes the construction of the Rainier Crosstown Connector that will connect McDowell Boulevard at Rainier Avenue to Petaluma Boulevard North. This bridge will provide an additional route for pedestrians, bicyclists and vehicles of residents and businesses to travel between the East and West sides of town, helping with crosstown travel traffic.

The new crosstown connector project will go under Caltrans’s new Highway 101 Rainier overcrossing and go over the Petaluma River and the SMART tracks. The new Caltrans overpass is being constructed with the MSN C2 Highway 101 widening project.

The project will include signal modifications at McDowell Boulevard, curb ramps, new roadway and bridge sections and a new intersection at Rainier Avenue and Petaluma Boulevard North.

PLEASE NOTE: There is currently no through connection.
