This design-build project involved the construction of 40.5 miles of track for the initial operating segment of the new Sonoma Marin Area Rail Transit (SMART) commuter rail system. Work included removal and reconstruction of track and track bed along with an existing alignment, of which 34.5 miles were under active freight traffic. Notable features of the work include bridge construction, grade crossings, extensive drainage work, and eight station substructures.
