The project also includes a two story building with five "swing gates" able to direct passengers arriving from outside of the US to a new FIS facility for US Customs and Border Protection of the first floor. Other features include a renovated lobby, an additional 16,000 sf for concessions, an expanded and reconfigured security screening checkpoint, and a new wing for Southwest Airlines passenger ticketing that can be accessed from the new parking garage. The concourse consists of a cast-in-place concrete pan formed beam system. The roof of the concourse was constructed out of structural steel.
