About the project:

SMART is extending its regional passenger rail service northward from Windsor to Healdsburg, reconnecting the city to rail transit.

The project will add roughly nine miles of track, construct a new SMART station in Healdsburg, and extend the SMART multi-use pathway for walking and biking alongside the rail corridor.

Critical infrastructure upgrades—including improved grade crossings, bridge rehabilitation, modern signaling, and safety systems—are part of the project.

A design-build contract was awarded in 2025, and passenger service is anticipated to start by late 2028.

The extension is funded through a combination of federal, state, regional, and local grants, reflecting strong support for expanding sustainable transportation, reducing congestion, and enhancing regional connectivity.

All construction updates will be available below once they are sent by email.
