Des Moines Airport’s New Terminal: A Glimpse into the Future of Midwest Travel
Des Moines International Airport (DSM) is on the cusp of a major transformation with the opening of its new terminal in January 2027. The $557 million project, years in the making, promises to alleviate overcrowding and accommodate the growing demand for air travel in Central Iowa. But beyond the immediate benefits, the new terminal signals broader trends shaping the future of regional airports.
From Enabling Projects to Modern Hub
The journey to a new terminal wasn’t simply about constructing a building; it was a decade-long process of strategic “enabling projects.” These included relocating air cargo facilities, Signature Aviation operations and hangars, as well as demolishing existing structures. According to Brian Mulcahy, CEO of the Des Moines Airport Authority, these foundational steps were critical. “I’m not sure we’d be here…if we didn’t start doing the enabling projects,” he stated.
Addressing Capacity and the Passenger Experience
The current terminal’s limitations are becoming increasingly apparent. Seating areas, designed for aircraft typically carrying over 100 passengers, currently accommodate only around 70 people. The new terminal aims to resolve this with seating for approximately 140 passengers in waiting areas, significantly reducing congestion. This focus on passenger comfort and flow reflects a growing industry trend towards prioritizing the overall airport experience.
The new facility boasts a wide-open design with high ceilings and abundant natural light, a departure from the often-cramped feel of older terminals. This design choice isn’t merely aesthetic; it’s intended to create a more welcoming and less stressful environment for travelers.
Phased Gate Expansion for Future Growth
The initial phase of the new terminal will introduce six new gates, bringing the total to 19. An additional gate will open in late 2027, with two more following in 2028, and the final two in 2030. This phased approach allows the airport to adapt to evolving airline needs and passenger volumes. The increased gate capacity will as well enable airlines to potentially expand destinations served from Des Moines.
Economic Impact and Regional Connectivity
Airports are increasingly recognized as vital economic engines for their regions. A report from the Iowa Department of Transportation’s Bureau of Aviation demonstrates that Des Moines International Airport generates approximately $752 million in annual economic activity for the state. Mulcahy emphasizes the airport’s role in attracting and retaining businesses, stating that strong air connectivity is “a matter of necessity on the business side” and a “quality of life issue” for residents.
Construction Innovation: The CMAR Model
The Des Moines airport project is among the first in Iowa to utilize the Construction Manager-at-Risk (CMAR) delivery method, approved by the state legislature in 2022. This collaborative approach, involving early engagement of the construction manager in the design phase, has reportedly accelerated the project timeline by at least six months, according to Mike Tousley, general manager of the Weitz Co.
Seamless Transition and Future Demolition
The transition to the new terminal will be a carefully orchestrated overnight operation. The current terminal will close after the last flight of the night and reopen in the new facility before the first flight the following morning. Following the transition, the existing terminal will be demolished, with the current concourses remaining connected to the new terminal via a skybridge until all new gates are operational. A new road will replace the demolished terminal.
