Sonoma-Marin Area Rail Transit (SMART) is a passenger rail service and bicycle-pedestrian pathway in Sonoma and Marin counties. Phase IOS1 and CP4 have been completed and are in service, and CEL has recently been contracted for the next phase, Larkspur Extension. When complete, the entire project will serve a 70-mile corridor between Cloverdale in northern Sonoma County and Larkspur Landing in Marin County. The first phase to open, Phase IOS1, is a 43-mile segment between Northern Santa Rosa and Downtown San Rafael, including the replacement of 13 bridges and station platform footings. The second phase, Phase CP4, added a bike path, the Petaluma bridge, and both San Rafael stations.
