The airport is attempting to update the $1.1 billion passenger terminal that opened in 2008, improve the passenger experience and create a sense of place by referencing iconic Indianapolis locations and people. Preliminary plans also call for more signage, including an outdoor welcome sign for arriving and departing passengers, and signs that more clearly identify each gate. The circular commons area between the ticketing counters and security screening sections, called Civic Plaza, could be subdivided into smaller zones including seating areas, a market-style area for vendors, and a contoured area covered with artificial grass that could be used for performances and events.
