On June 7, 2006, plans were announced to replace Terminal B with a brand new terminal by the year 2012. In 2008, the Sacramento County Airport System broke ground on the largest capital improvement project in the history of the County of Sacramento: "The Big Build". The expanded Terminal B was designed by Corgan Associates, Inc. in association with Fentress Architects. The landside (pre-security) portion of Terminal B was built by the joint venture of Austin Commercial, LP and Walsh Construction, and the glass and aluminum facade was constructed by AGA (Architectural Glass and Aluminum). The airside gates and light rail train were built by Turner Construction. The $1.03 billion terminal modernization project replaced the airport's original, aging Terminal B to meet the rising demand for passenger services and improved the airport's ability to attract new carriers and routes.
