State Route 37 follows 21 miles along the northern shore of San Pablo Bay linking US 101 in Novato, Marin County with Interstate 80 (I‐80) in Vallejo, Solano County. It serves as a vital connection between Marin , Sonoma , Solano and Contra Costa and the Central Valley. It is the northernmost non‐mountainous east‐west link between US 101 and I‐5 (via I‐80 and I‐505) in the State.
Think about Highway 37 as more than just a commute! The future of this corridor demands finding solutions to chronic traffic congestion and periodic flooding. But it will also require balancing transportation needs with protecting and enhancing sensitive marshland habitats. Planning a long-term solution presents an opportunity to provide bicycle, pedestrian, transit, and carpool options for all travelers. For more information, visit the Resilient 37 page.
Growing housing demand in the North Bay counties has produced a housing market that a high percentage of household cannot afford. Consequently, many have to live far away from their jobs. This jobs/housing imbalance is one cause of congestion Bay Area wide, and specifically for SR 37. Average Annual Daily Trips are projected to increase from 45,000 in 2013 to 58,000 by 2040.
SR 37 is protected by a complex system of interconnected levee which makes the corridor vulnerable to Sea Level Rise inundation and flooding now and in future.
In December 1, 2015, the Congestion Management Agencies (CMA) of Marin, Napa, Solano and Sonoma Counties agreed to form a partnership through a Memorandum of Understanding (MOU) to develop an expedited funding, financing and project implementation strategy for the reconstruction of SR 37 to withstand rising seas and storm surges while improving mobility and safety along the route.
