First post-9/11 airport
Indianapolis International Airport, located 7 miles southwest of Downtown Indianapolis, Indiana, opened its new passenger terminal on November 12, 2008. It was the first airport in the US to be designed and built from scratch following the September 11 attacks.
The airport's history dates back to the late 1920s when the city of Indianapolis and its council discussed developing a municipal airport. In 1929, the city purchased 320 acres on South High School Road for a landing area and an additional 627 acres for future expansion. The Indianapolis Municipal Airport, the first in the area with concrete runways, was constructed on this site.
Over time, the airport underwent several changes and expansions. In 1944, it was renamed the Weir Cook Municipal Airport in honour of H. Weir Cook, a World War I fighter ace and Hoosier native. The airport's first airline traffic operated on February 16, 1931, and it officially opened on September 25, 1931. By the 1950s, the airport was feeling crowded, and a new terminal was built in 1956.
In 1976, the airport was renamed Indianapolis International Airport, and efforts were made to expand and upgrade its facilities to accommodate international flights. However, the current terminal, named the Col. H. Weir Cook Terminal, opened in 2008, is a significant upgrade. It was designed by the international engineering and architecture firm HOK, costing $1.1 billion to build. The terminal covers 1.2 million square feet and features a central gathering point called Civic Plaza, which includes concessions, retail stores, security checkpoints, artwork, and public event spaces. The terminal incorporates sweeping changes in US airport security protocols post-9/11 while also focusing on sustainability and energy efficiency.
