Pacific Gas & Electric (PG&E) Valve Lot Relocation Project

The Solano Transportation Authority (STA) proposes to relocate an existing Pacific Gas & Electric (PG&E) valve from its current location between Interstate 680 and Lopes Road in the City of Fairfield.  The valve lot would be relocated to a parcel of vacant land on the east side of I-680, approximately 0.2 miles to the east of the exisitng lot.  New gas pipelines would be constructed to connect existing transmission lines in the project area to the relocated valve lot.  Once the relocation is complete, the existing valve lot and associated pipelines would be deactivated.

I-80/I-680/SR-12 Interchange Project

 

The Solano Transportation Authority (STA), and its project partners, Caltrans, and the Metropolitan Transportation Commission (MTC) are working together on major improvements to the Interstate 80, Interstate 680 and State Route 12 interchanges.

This multi-year, multi-phase project is located in Solano County. The southwest project limits are near Fairfield's Green Valley and Cordelia neighborhoods, the northeast project limits near Suisun City.

Once completed, the project will improve safety and travel times for motorists on I-80, I-680, Highway 12 and adjacent city streets. Features include a realignment of I-680, an improved direct connector route between I-80 and Highway 12, construction of new interchange overcrossings, new entrance/exit ramps, bike and pedestrian safety improvements, and the extension of some local streets leading to I-80 and Highway 12.

The project will benefit citizens by improving travel times, reducing cut-through traffic on local streets, and enhance safety by streamlining connections for motorists transitioning between these three major state routes linking the Bay Area, the Napa Valley, and Sacramento.

The Final Environmental Impact Report/Environmental Impact Statement (EIR/EIS) is available for public review. 

The multi-year project includes several environmentally cleared design packages.  Package I through Package VII.

Package II

Package III

Package IV

Package V

Package VI

Package VII

**Project Updates***

On March 14, 2012, the STA Board determined that the Acquisition of Properties for the Interstate 80/Interstate 680/State Route 12 Interchange Project Initial Construction Package will not have a significant effect upon the environment and is exempt further procedures under the California Environmental Quality Act (CEQA).  Download the Notice of Determination for the "Acquisition of Properties for the Interstate 80/Interstate 680/State Route 12 Interchange Project Initial Construction Package, 03-14-2012.

The groundbreaking ceremony for package 1 (Green Valley Interchange Project) was held on June 2ndConstruction could be completed as early as summer 2016. Package II through Package VII will be constructed and completed subject to funds available. Each package will be constructed under separate contracts with each subsequent package starting and finishing in 2015 and beyond.

I-80 HOV Express Lanes Conversion Project

The I-80 Express Lanes project will cover the existing High Occupancy Vehicle (HOV) lanes as well as new construction from Air Base Parkway to I-505.  The anticipated construction start date is August 2014.

The project was completed in November 2009, adding over eight miles of HOV lanes in both directions and widening the median on I-80 from approximately Red Top Road to Airbase Parkway. The HOV lanes are now open from 5:00 a.m. to 10:00 a.m. and 3:00 p.m. to 7:00 p.m. Monday through Friday for vehicles with 2 or more occupants.

As a busy trade, travel and commuting corridor, there are approximately 150,000 vehicles traveling on Interstate 80 each day. This number increases to more than 200,000 vehicles per day through the City of Fairfield. The new carpool lanes will enhance capacity by encouraging motorists to rideshare and reduce the number of vehicles on the highway.

HOV lanes play a crucial role in helping to support more sustainable transportation choices by providing an incentive to carpool, vanpool or take a bus. This Proposition 1B Corridor Mobility Improvement Project (CMIA) was the first CMIA project in the Bay Area. In addition to the carpool lanes, this project also provided a new concrete median barrier and wider bridges to accommodate the new lanes. Click here for more information on Prop 1B funding.

Caltrans programmed over $140 million of State Highway Operations and Protection Program (SHOPP) rehabilitation projects for I-80 between Vacaville and Vallejo. This project started in Fiscal Year (FY) 2007-08 with work in the cities of Vacaville and Vallejo, and occurred concurrently with the construction of the new I-80 HOV lanes project.

The rehabilitation project provided a new concrete median barrier and wider bridges to accommodate the new lanes.  A ribbon cutting ceremony for the new carpool lanes and three paving rehabilitation projects completed in 2009 was held on November 5th in Fairfield.

Local Interchange Projects - I-80 Redwood Parkway-Fairgrounds Dr. Improvement Project, Vallejo

I-80 High Occupancy Vehicle LanesThe proposed project would include roadway improvements along portions of Fairgrounds Drive and Redwood Parkway/Redwood Street, and several nearby intersections and interchanges within the City of Vallejo. The project would widen and improve 1.5 miles of Fairgrounds Drive, extending from the State Route 37 interchange to the Redwood Parkway/Interstate 80 interchange. In addition, a number of intersections and interchanges would be improved, including Redwood Street/Parkway and Interstate 80, Fairgrounds Drive and State Route 37. Several local streets would require improvement or modification, including Moorland Street and Redwood Street, Redwood Parkway, and Admiral Callaghan Lane.  The purpose of the Project is to relieve congestion and improve traffic flow on local streets; improve the existing interchange and intersection operations; improve the safety of local streets; and increase capacity of the local roadway network to support future growth in the area.

This project has been evironmentally cleared and is prepared for the design and construction phase, which will begin in 2015.

A public meeting was held on January 18, 2012 at Cooper Elementary School, located at 612 Del Mar Avenue in Vallejo California to provide information and answer questions about the proposed project.
