Twin Cities Airport

The primary reason for its closure was replacement. A new, larger, and more modern facility, the current Fort Smith Regional Airport (KFSM), was constructed south of the Arkansas River. The new airport opened in 1953, making the original Twin Cities Airport obsolete for commercial traffic and eventually for all aviation as urban and industrial development expanded in the area.

The site has been completely redeveloped into the Van Buren Industrial Park (also known as the Airport Industrial Park). While the airport itself is gone, distinct remnants of its X-shaped runway and taxiway layout are still visible from satellite imagery. Portions of the original paved surfaces have been repurposed as access roads (like Airport Industrial Park Road) and parking lots for the numerous industrial and manufacturing facilities that now occupy the land.

Originally known as Fort Smith Municipal Airport, this was the first major airport for the 'Twin Cities' region of Fort Smith and Van Buren, established around 1940. It was a significant transportation hub, handling scheduled passenger service from major carriers of the era, including Braniff Airways and Mid-Continent Airlines. During World War II, the airport had strategic importance, serving as a contract glider training school for the U.S. Army Air Forces' 3rd AAF Glider Training Detachment. After the war, it resumed its role as the area's primary commercial airport until the new facility was built. The ICAO code US-10000 is a non-standard identifier; its original IATA code was FSM, which was transferred to the new airport upon its opening.

There are zero plans or prospects for reopening the airport. The land has been fully and permanently repurposed for industrial use for several decades. The region's aviation needs are comprehensively served by the nearby Fort Smith Regional Airport (KFSM).
