STV joined California’s Sonoma-Marin Area Rail Transit (SMART) to celebrate the opening of the new Windsor commuter rail station and a 3.2-mile extension of its passenger rail line.
The milestone event marks a significant advancement in SMART’s mission to expand sustainable, multimodal transportation throughout California’s North Bay region.
As SMART’s design partner, STV provided comprehensive design services for the Windsor extension. The scope included rail, civil, and structural engineering; station architecture; bridge and roadway design; and the integration of a non-motorized pathway alongside the track.
The extension adds 3.2 miles of reconstructed railroad track from the existing Sonoma County Airport Station to downtown Windsor. Highlights of the project include:
A newly constructed passenger station in Windsor.
Five rebuilt rail bridges span regional streambeds.
Two pedestrian bridges.
A pedestrian underpass.
A new parking facility.
Upgraded railroad grade crossings with modern safety features.
An adjacent non-motorized pathway to enhance walkability and bike access.
“The opening of the New Windsor Station marks a significant step toward completing a regional rail vision more than 30 years in the making,” said Andrew Sokol, vice president and engineering director at STV. “STV is proud of our long-standing partnership with SMART, and we are excited to help them bring newer, safer, and more resilient regional rail options to the North Bay communities.”
The Windsor extension is a key milestone in SMART’s broader plan to establish a 70-mile passenger rail corridor connecting Larkspur to Cloverdale, with 16 total stations along the route.
The project aims to support local tourism, improve regional connectivity, and reduce environmental impacts by promoting transit-oriented development.
STV has played a central role in the corridor’s development, having designed 45 of the 48 miles of SMART’s rail line. This work includes the design of 11 stations, more than 30 bridges, and 80 grade crossings.
