STA is partnering with the Sonoma County Transportation Authority (SCTA), the Napa Valley Transportation Authority (NVTA) and the Transportation Authority of Marin (TAM) to address both chronic traffic congestion and flooding risk from dangerous sea-level rise on State Route 37. MTC has committed $100 M from Regional Measure 3 funding to:
Fund improvements to SR 37 to provide for mobility, safety and resiliency to sea-level rise and flooding. The project includes the segment of SR 37 from the intersection with U.S. Highway 101 in Marin County to the intersection with Interstate 80 in Solano County.
Please check back here or with our partners at SCTA for updates on this transformative, regionally significant resiliency project in the near future. See the Updates tab for related Project Documents.
