Last month, Kansas City International Airport broke ground on a new $1.5 billion single terminal. The airport is currently laid out in a three-terminal configuration, and remained mostly unchanged since it opened in 1972.

Now, the new construction will help accommodate passenger traffic that has nearly tripled since opening.

The new terminal will be the largest infrastructure project in the Missouri city’s history. The building is designed by Chicago-based Skidmore, Ownings & Merrill and will offer 1 million square feet with 39 gates; it is expected to create 5,000 jobs.

“A modern airport that is attractive to passengers and airlines is an important competitive advantage for any major metropolitan area,” Tim Cowden, CEO, Kansas City Area Development Council, said in a statement. “KC has a long track record of investing in its cultural assets, major league sports facilities, roads, bridges and mass transit options, and a new single terminal at KCI is the next important phase in our region’s growth.”

To complement the expansion, the airport is also working on other projects, including more parking, a two-level curbside pick-up and drop-off area; expanded flight options and waiting areas at each gate to accommodate an increased number of passengers and larger aircraft; and a revamped travel experience with more post-security amenities.
