Proposed Toll on Highway 37
The Resilient 37 Program partners, which include MTC and its Bay Area Infrastructure Financing Authority affiliate, propose a toll on state Route 37 to help meet regional transportation and environmental goals.
State Route 37 is a key 21-mile link between Solano County, Napa County, Sonoma County and Marin County. The route experiences a high level of traffic congestion and seasonal flooding.
The Resilient 37 Program is addressing these challenges with short-term improvements to be implemented over the next few years as well as long-term improvements that likely will take decades to deliver.
Proposed Toll
Short-term improvements to Highway 37 include expanding the roadway from one lane in each direction to two lanes in each direction between Sears Point and Mare Island. In each direction, one lane would remain free-of-charge for eligible carpool vehicles, while the other lane would be a tolled lane.
This project is expected to cost $500 million and open to the public in 2030.
The proposed toll would support shorter commute times, improved road conditions, increased travel options and improved air quality for all who travel Highway 37 between Sears Point and Mare Island.

Frequently Asked Questions
Why is the Resilient 37 Program proposing a toll?
Adding a toll on SR 37 will help meet three important goals:
- The State of California requires a reduction of greenhouse gas emissions and a reduction of the overall number of vehicle miles traveled (VMT).
- The toll will be an important source of funds for construction. A local funding source will help the project secure match funding from the state and federal governments.
- A more resilient Highway 37 improves quality of life in the Bay Area.
What are the benefits of a toll?
- Reduced commute times. A new lane in each direction could reduce commute times by 30 to 60 minutes or more.
- Improved road conditions. The toll will support ongoing road maintenance.
- Increased travel options. The toll will support transit and commuter programs that provide reliable alternatives to driving alone.
- Improved air quality. Less congestion will reduce vehicle emissions and improve air quality.
What will the toll cost?
Toll rates are expected to be similar to those on Bay Area toll bridges. MTC is looking at potential discount programs for qualifying low-income drivers.
