# MidAmerica St. Louis Airport

MidAmerica St. Louis Airport (IATA: BLV, ICAO: KBLV, FAA LID: BLV) – also known as Belleville–St. Louis Airport – is a public use airport next to Scott Air Force Base. It is located 18 nautical miles [nmi] (33 km; 21 mi) east of downtown St. Louis and 14 nmi (26 km; 16 mi) east of the central business district of Belleville in St. Clair County, Illinois, United States. Opened in 1997, MidAmerica is the secondary domestic passenger airport for the Greater St. Louis metropolitan area, after the larger St. Louis Lambert International Airport. It is a joint-use airport and is currently served by one scheduled commercial airline, Allegiant Air.
The airport had 152,278 passenger enplanements in 2018 (302,000 total passengers), according to the Federal Aviation Administration. It was included in the National Plan of Integrated Airport Systems for 2017–21, which categorized it as a primary commercial service airport because it surpassed 10,000 annual enplanements. It is the fifth-busiest of the 12 commercial airports In Illinois.

## History

MidAmerica St. Louis Airport was created to alleviate crowding at St. Louis Lambert International Airport, but had been criticized as a pork barrel project. Featured several times on a "Fleecing of America" segment on the NBC Nightly News, it was called a "Gateway to Nowhere" by Tom Brokaw, costing taxpayers $313 million. Congestion at Lambert Airport has not been a problem since American Airlines ended hub operations at the airport and a new billion-dollar runway opened in 2006.
As of 2021, nearly $125 million of St. Clair County taxpayer funds have been spent covering the airport's deficits. The airport's biggest revenue source is fuel sales to Boeing, which test-flies drones for the U.S. Navy. The airport will be paying its construction debt from 1995 until 2045, costing taxpayers an additional $88 million.
Supporters credit MidAmerica's additional runway with saving Scott AFB from closure during the 2005 Base Realignment and Closure process. They also describe MidAmerica as a "Gateway to the World", citing a new cargo terminal and customs facility designed to handle international cargo.
Passenger service has increased since Allegiant Air restarted service in 2012 with flights to 12 destinations. In 2018, MidAmerica Airport was named "Airport of the Year" for airports that see more than 10,000 passengers annually by the Illinois Department of Transportation. In 2021, a Bureau of Transportation study found it among the nation's five least-expensive airports.

### Flight testing

In late April 2019, the first MQ-25 Stingray test aircraft (T-1 or "Tail 1") was taken by road from Boeing's technical plant at St. Louis's Lambert International Airport across the Mississippi River to MidAmerica St. Louis Airport, which is conjoined to Scott Air Force Base. Test flying was expected to commence at MidAmerica late in 2019, after taxi tests and the Federal Aviation Administration’s certifying the aircraft and granting airspace for flight testing. The first test flight occurred on September 19, 2019.
In Addition: "Boeing plans to build three new, state-of-the-art facilities in St. Louis ... These facilities, as well as the new Advanced Composite Fabrication Center in Arizona, and the new MQ-25 production facility at MidAmerica St. Louis Airport, represent more than a $1 billion investment."

## Facilities
### Passenger facilities

From the onset, the passenger terminal was planned for easy expansion if needed. The passenger terminal sits in a 250-foot-wide by 700-foot-long expansion envelope bounded by a runway and parking lot. The initial build-out has two upper-level departure gates with jet bridges and some ground-level gates to serve smaller commuter aircraft.
In September 2020, the airport received $6.5 million in federal grants to expand the terminal. There are four phases to the terminal expansion. The first phase was completed in spring 2020. The second phase began in late 2020 and was to be completed in 2021. The final phase is to be completed by the end of 2023. The project will add 41,000 square feet to the existing terminal. This space will be used for a relocated and upgraded security checkpoint, two additional jet bridges, a service animal relief area, family restrooms, a nursing room, an expanded departure lounge and added room for concessions. It will also better accommodate people with disabilities.

* Runway 14R/32L: 8,006 by 150 feet (2,440 x 46 m), surface: asphalt/concrete, ILS equipped
MidAmerica's construction included the creation of the 10,000-foot (3,000 m) 14L/32R (east) runway, adding 1,000 feet (300 m) to the existing west runway, adding passenger and cargo terminals on the east side of the facility, and building a 7,000-foot (2,100 m) taxiway connecting the two runways. A new air traffic control tower staffed by Air Force personnel was constructed midway between the two runways.
In September 2022, construction began on an extension to Taxiway Lima as well as a new Taxiway Bridge over Crooked Creek to connect the airport to a new aviation business park. Taxiway construction was completed in 2023. A new Boeing Production Facility is already underway as the first tenant to build the MQ-25 unmanned aircraft.

### Maintenance and operations

The civil operations are administered by St. Clair County, Illinois, which also pays the maintenance costs for the east runway. Over half of all air operations at the facility utilize the eastern runway.

Both Boeing Defense, Space & Security and North Bay Produce currently have facilities on site. North Bay Produce primarily ships blueberries from Michigan and Chile into the airport; they use a completely refrigerated warehouse for packaging and distribution. Boeing uses the facility at MidAmerica for sub-assemblies for multiple military aircraft.

## Public transportation

The St. Clair County Transit District (SCCTD) operates the MidAmerica Airport Shuttle, which offers service between the airport and the Shiloh–Scott station of MetroLink, the St. Louis region's light rail system. The trip takes about 20 minutes, with buses arriving every 40 minutes, starting three hours prior to the first scheduled flight of the day and continuing until 35 minutes after the last flight of the day.
From Shiloh–Scott station, the Red Line provides direct service to downtown St. Louis. Additionally, MetroLink provides direct or indirect service to the Central West End, Clayton, Lambert Airport, and suburban areas in both Illinois and Missouri.
SCCTD is planning a 5.2-mile (8.4 km) extension of MetroLink from Shiloh–Scott station to the MidAmerica St. Louis Airport station at MidAmerica Airport. The expansion will include a 2.6-mile (4.2 km) double-track section, a 2.6-mile (4.2 km) single-track section and a passenger station at the end of the alignment near the airport. The project received $96 million in funding from the State of Illinois in 2019. Design work was completed in the summer of 2022 and a request for proposals was released that November. The extension is expected to be operational by spring 2025.
