I-680 Repaving Project (Caltrans SHOPP Project)
I-80/I-680/SR-12 Interchange Project
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
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.
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.
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.
multi-year project includes several environmentally cleared design packages. Package I through Package VII.
April 2015 Project Status Update
The groundbreaking ceremony for package 1 (Green Valley
Interchange Project) was held on June 2nd. Construction 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.
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).

I-80 High Occupancy Vehicle (HOV) Lanes (Fairfield)
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.

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