Rebuilding State Route 37 to elevate it above water in the face of rising sea levels got a welcome $155 million boost from the $1.2 trillion U.S. infrastructure Law of 2021, the California Transportation Commission announced this week. The two-mile Marin County section of the 21-mile commuter artery that runs alongside San Pablo Bay connecting Marin, Sonoma, Napa and Solano counties marks the beginning of a larger $4 billion project planned for the whole corridor. State transportation officials say work is expected to start in 2027 and end two years later. The $180 million project approved Aug. 18 by the state’s transportation commission will raise the roadway by 30 feet over Novato Creek by 2029, well above the projected year 2130 sea-level rise.
