Construction Updates



SMART Larkspur Extension Project

SMART began construction of its rail extension to Larkspur in July 2017. The extension to Larkspur includes 2.2 miles of track connecting San Rafael and Larkspur, a terminal station in Larkspur Landing, three bridges, and utilizes the recently rehabilitated Cal Park Tunnel that currently provides a bicycle/pedestrian connection to Larkspur from San Rafael.

Following construction of the Larkspur Extension, safety signals and systems will be thoroughly tested prior to the start-up of service to Larkspur Landing. SMART train service to Larkspur is projected to begin in late 2019. 

For more information about the Larkspur Extension Project, call the Larkspur Extension Project Hotline: 800-959-8660.
