Solano Area is proud to serve our community providing safety, service, and security. As part of the CHP’s Golden Gate Division, traffic flowing through Solano County is some of the busiest seen north of the Los Angeles Metropolitan Area. Each day, nearly 200K vehicles pass through the junction of Interstates 80 and 680. These vehicles are a mix of large commercial trucks, visitors heading west to the coast or east to the Sierra Nevada Mountains, and some of the county’s nearly half-million residents. I-505 is used by Bay Area traffic to connect with I-5, the primary route to Oregon and Washington State, while State Route 12 (SR-12) carries traffic to both the Sacramento River Delta and the Napa Valley and their countless recreational draws. State Route 37 is the link to many recreational destinations around U.S.-101, “The Redwood Highway.” We offer a number of programs aimed at keeping you safe on the road and highway. You can help us by always wearing your seatbelt and driving defensively. Thank you for taking the time to visit our web site.

The first official seal of Solano County was adopted by the Board of Supervisors on April 20, 1965. The seal is rich in symbolism that reflects the history and values of Solano County.
The pillars from the Old State Capital building in Benicia are incorporated into the border of the design. Dominating the outline of the county is the figure of Chief Solano, for whom the county is named. Inside the county outline you can see the vast agriculture area surrounded by blue skies, mountains and waterways.
The U.S. Armed Forces are part of Solano County – both past and present. The large aircraft reflects the mission of Travis Air Force Base and the ships reflect the former Mare Island Naval Shipyard.
The golden rays indicate the benign climate Solano County residents enjoy, and the recreational boat showcases the outdoor amenities that abound in the county.
