All Significant Work Completed
The STA, working closely with law enforcement agencies and Caltrans, has developed a multi-faceted strategy for improving safety and mobility on this important interregional highway route from Rio Vista to Suisun City and Fairfield. The four key elements of the program are enforcement, legislation, public education and signage, and engineering.
Project Study Report: Caltrans, in partnership with STA, has completed a study of the proposed improvements at the intersection of SR 12 and Church Road-Amerada Road. The improvements include the addition of right turn/eft turn lanes and acceleration/deceleration lanes along SR 12 in the east-west directions, the addition of left turn lane on Church Road approach and realignment of the intersection to eliminate the offset between Church Road and Amerada Road.
Envinronmental Document Completed and Adopted: In November 2016, Caltrans and STA adopted a Negative Declaration Initial Study Report. This report found no sigificant impacts from this proposed project. The Initial Study Negative Declaration can be found here:
State Route 37 Studies and Resources
Solano County, in conjunction with Napa, Sonoma, and Marin Counties, are studying the feasibility for the improvement of SR 37 to be more adaptable to sea level rise and to ease congestion on certain stretches that are only 1 lane in each direction. As a vital east-west connector, issues need to be identified, stakeholders communicated with, and options for improving SR 37 considered. A fact sheet for the project can be found here: SR37 Fact Sheet. You can find a presentation from August 24th to Caltrans here: SR37 Update Presentation to Caltrans
The Sonoma County Transportation Authority's Hwy 37 Website offers additional information as well.
Below is a list of recent studies and resources regarding the condition and potential future conditions of SR 37.
***Update April 2018***
On April 11, 2018 the STA Board accepted the SR37 Transportation and Sea Level Rise Corridor Improvement Plan. This plan includes typical corridor concept elements: goals and objectives, corridor issues, potential strategies for improvements, an implementation plan and next steps. This plan was built upon previous studies completed by UC Davis and Caltrans and highlighted the corridor's environmental sensitivity, vulnerability to flooding and congestion. It also framed the magnitude of potential cost for transportation improvements on the corridor.
The objective of the Plan was to introduce corridor concepts that will be further analyzed as part of three distinct segments of the corridor. Solano County is included in Segments B (SR 121 to Mare Island Interchange) and Segment C (Mare Island to I-80). The plan also identified Segment B as the priority segment for improvements related to sea level rise and congestion. This was a precursor to begin developing a Caltrans' required Project Initiation Document (PID) followed by the environmental phase for transportation improvements within Segment B.
***Update March 2018***
On March 14, 2018, the STA Board adopted the STA Guiding Principles for the SR 37 Corridor environmental process. The full text of the principles can be viewed here.
***Update December 2017***

Informational Open House on the Highway 37 Improvement Plan
In response to impacts from sea-level rise, flooding and increased traffic along the corridor, the counties of Marin, Napa, Sonoma and Solano, in partnership with Caltrans and the MTC, are planning to improve access and safety along Highway 37.
The Open Houses:
Monday, Oct. 2nd
Our facebook page has photos from the evening of information.
The 3 other participating counties held Open Houses during September.
Contact Daryl Halls, STA Executive Director, 707-424-6075, email@example.com with questions regarding this meeting.
September 20th Open House in Novato:
Here is KRON Channel 4's 3-minute video coverage of the SR 37 open house meeting held September 20th in Novato:
***Update February 2017***
Due to heavy and persistnent rains duing the month of January, SR37 was closed for flooding for 13 days. Caltrans provided an update about the flooding to the STA Board on February 8th. The presentation can be viewed here: Caltrans Update on SR37 Flooding
***Update December 2016***
The SR 37 Policy Committee have met twice and unanimously recommended that the Sonoma, Napa, and Marin CMAs participate with financial contributions on the STA's SR 37 P3 Corridor Study. However, this recommendation also included a broader scope with a modified title of SR 37 Corridor Financial Opportunities Analysis.
In summary, the modified scope of work is for a consultant or consultant team to act as a financial advisory resource for the SR 37 Policy Committee as the committee continues to investigate financial opportunities to improve the corridor. The scope includes case study examples of P3 and full privatization finance options, a decision making toolkit for pursuing any one of those financial examples, and a planning level toll revenue forecast.
The expanded scope of work is estimated for the SR 37 Corridor Financial Analysis is $85,000; however, STA's budget share would decrease overall by $20,000 based on the following four County CMA contributions:
***Update October 2016***
On October 12th, 2016 the STA Board approved a partnership with the Transportation Authorities of the Counties of Marin, Napa and Sonoma, and MTC to develop a State Route 37 Transportation and Sea Level Rise Corridor Improvement Plan. STA is also seeking to partner with Caltrans to conduct Public Outreach for the plan.
