On February 10, 2010, the STA board adopted the Solano Highways Operations Study.

Previously called the "I-80/I-680/I-780 Corridors Highway Operations Study & Implementation Plan", the study analyzes the performance and safety of Solano County's interstate highway corridors and recommends a varierty of operations improvements as well as visual guidelines for landscape and hardscape treatments.

This study was developed through the Solano Highways Partnership (SoHIP), which includes staff from the Solano Transportation Authority (STA), the Metropolitan Transportation Commission (MTC), the Sacramento Area Council of Governments (SACOG), Caltrans District 3 and District 4, and the cities of Benicia, Dixon, Fairfield, Vacaville, and Vallejo.

Cordelia Truck Scales Relocation Study

This study identifies potential sites that could satisfactorily accomodate the relocation of the existing scales within the I-80/I-680/SR12 Interchange or at other sites in Solano County.

The Cordelia Truck Scales, located on I-80 between Suisun Valley Road and SR12 (East), were built in 1958 and are currently undersized. The scales significantly contribute to the congestion on I-80 due to the large number of trucks exiting and entering I-80 and the close proximity of the scales to both the Suisun Valley Road and I-80 interchanges.

Solano Express Lanes Priority Project List

An Express Lane toll, or High-Occupancy Toll (HOT), is a toll enacted on single-occupant vehicles that wish to use lanes or entire roads that are designated for the use of High-Occupancy Vehicles (HOVs, also known as carpools).  Tolls are collected either by staffed toll booths, automatic number plate recognition, or electronic toll collection systems.


HOT lanes require single-occupant vehicles to pay a toll that varies based on demand, called congestion pricing.  The tolls change throughout the day according to real-time traffic conditions to manage the number of cars in the lanes and keep them free of congestion, even during rush hour. The concept proposed by the Metropolitan Transportation Commission (MTC) is an expansion of HOV lanes and an attempt to maximize their efficiency in moving vehicles throughout the Bay Area.  HOV lanes are designed to promote vehicle sharing and use of public transport by creating areas of lower road use as an incentive, but they have been criticized because some are underused and increase congestion.  The HOT lanes provide a mobility option for single occupant vehicles to provide reliable travel at a variable price.


In February 2009, the STA Board approved an Express Lanes Priority Project List, should the STA be successful in gaining financial resources from MTC/BATA for the funding of the HOV/HOT projects within Solano County.

MTC Freeway Performance Initiative

With opportunities for highway expansion limited due to environmental, financial and other factors, MTC in 2007 launched the Freeway Performance Initiative, or FPI, to attain more capacity on existing roadways.  The program targets predictable congestion caused by commuters using the freeways during rush hours as well as non-recurrent congestion resulting from unanticipated incidents.

Caltrans Corridor System Management Plan (CSMP)

The goal of a Corridor System Management Plan (CSMP) is to define how a travel corridor is performing, understand why it is performing that way, and recommend system management strategies to address problems within the context of a long-range planning vision.  Guided by the system management pyramid, a CSMP seeks to incorporate operational analysis into more traditional transportation planning processes at the corridor level.  This is accomplished by conducting comprehensive performance assessments, analysis and evaluations leading to recommending system management strategies for the corridor. 


Each CSMP is developed in concert with, and in consideration of, State, local and regional goals, including, but not limited to, local and regional mobility, transportation system connectivity, regional blueprint planning, context sensitive transportation solutions, and encouraging the use of alternative transportation modes.

SR 12 Corridor Study (I-80 to I-5)

STA partnered with Caltrans, the Metropolitan Transportation Commission (MTC,) the San Joaquin Council of Governments (SJCOG) and Sacramento County on an 18-month study of the future of State Route (SR) 12, from I-80 to I-5.  The study built upon existing information from STA and SJCOG/Caltrans studies of segments of the route, improvements that are underway or have been recently completed in Solano and San Joaquin counties, and future roadway needs projected through 2035.  The study looked at current and future constraints on the roadway, including the Sacramento River, Mokelumne River and Potato Slough bridges, wetlands in both Solano County and the Delta, and impacts of projected sea level rise.  The study analyzed 4 options for the corridor:

  1. No improvements other than those already approved and funded
  2. Improvements to develop the corridor to 2 lanes plus full shoulders, turn lanes and passing lanes for its entire length
  3. Improvements to develop the corridor to 4 lanes plus shoulders and turn lanes for its entire length
  4. A complete realignment of the corridor. 

The study, completed in June 2012, recommended operation and safety improvements along the entire corridor, including construction of a 4-lane divided highway from the SR 12/SR 113 intersection to a location east of SR 160 in Sacramento County, replacement of the Sacramento River and Mokelumne River bridges, and installation of an extensive network of cameras, traffic monitors and changeable message signs.  The final report was released in November 2012:

The SR 12 Corridor Advisory Committee (CAC) met on April 18, 2011.  The following materials were provided as an update to the ongoing study:

A Stakeholder Meeting was held July 26, 2011 at the City of Lodi Public Library at 3:00 pm to review Future Conditions and Potential Improvement Strategies.

SR 113 MIS

On May 19, 2006, Caltrans approved the award of a $250,000 Grant to STA to complete a Major Investment and Corridor Study for SR 113.  This was one of only four statewide grants approved by Caltrans that year.

The purposes of the study included:

  1. Form a multi-jurisdictional partnership with Caltrans, MTC, the Sacramento Area Council of Governments (SACOG), STA and other agencies.
  2. Identify and study SR 113 alignment alternatives.
  3. Identify funding options to improve SR 113 (including the investigation of a toll lane option).
  4. Implement an extensive public outreach to those potentially affected by operational and safety improvements to SR 113.
  5. Deliver results based on an aggressive planning implementation schedule.
  6. Create Planning deliverables beneficial to Caltrans and other members of the SR 113 Corridor Partnership.

The SR 113 Major Investment and Corridor Study (MIS) recommends short, medium and long range safety improvements along the SR 113 Corridor and describes four (4) potential alternatives for realigning SR 113 to I-80 away from the Dixon downtown area.  STA staff presented these alternatives at several public input meetings in August and September 2008, including Davis and Dixon City Councils, Solano County Board of Supervisors, and the Yolo County Transportation District.  The final draft SR 113 MIS includes the input received from these meetings.

Oakland to Auburn Regional Rail Study

This report documents a conceptual service plan and implementation strategy for provision of new regional rail (commuter) service in the urban corridor extending from Auburn to Oakland, California. The new service would augment existing Capitol Corridor intercity service by providing additional peak period capacity within the greater Sacramento urban area and between Sacramento and the Bay Area. The two services (Capitol Corridor and Regional Rail) would utilize the same equipment, staff, and fare structure, and thus would appear fully unified to the riding public.

Transit Consolidation Study

Over the past several years, the issue of consolidating some or all of the six city-operated Solano transit services has been discussed and proposed for study. This topic was discussed by the STA Board and they expressed interest and support for transit service becoming more convenient through a seamless system, delivering a reasonable level of service throughout the county, and addressing local transit issues and need.

The STA Board approved goals, objectives and evaluation criteria to be incorporated in the scope of work for this study. A consultant team, lead by DKS Associates, was selected to conduct a countywide Transit Consolidation Study which began in early 2007. The first phase of this study was to conduct extensive outreach with stakeholders. Consultants completed nearly 60 interviews and held three rider focus groups to identify their perspectives, issues, and concerns concerning potential transit consolidation.

Initial reports on the findings of current transit services, perspectives, and trends as well as reports presenting potential transit consolidation options were released in Fall 2007:

Options Report
Options Report Executive Summary

At the end of Phase I, the STA Board also appointed a Transit Consolidation Steering Committee which has been guiding this study.  Phase II of this effort involved a review and analysis of the existing six transit operators and seven consolidation options. The STA Board approved the following recommendations at their meeting on June 10, 2009.

  • Option 1:  Consolidation of Benicia and Vallejo transit services pursuant to guiding principles;
  • Option 4c:  Decentralize intercity paratransit service to local transit operators and continue study of consolidation of interregional Solano transit services under one operator to be selected by the STA Board;
  • Forward the STA recommended transit consolidation recommendations to the affected agencies for their consideration and participation;
  • Direct STA staff to work with the affected local transit staff to develop Implementation Plans for Option 1 and Option 4c; and
  • Report back to the STA Board by September 2009 on the status of the Implementation Plan.
