Now hosting Green Mountain Avionics and J&M Aviation, the airport supports local, college, and regional needs. The original airport facility was developed by the Quesnel Family in the 1950s in support of their aerial application, flight instruction, and maintenance business. In 1966, the Town of Middlebury purchased the facility. In 1970, it was acquired by State of Vermont Aeronautics Board and f
ormally named "Middlebury State Airport". In 1976 the Army National Guard constructed a gravel taxiway parallel to the runway. In 1990, a tie-down apron was constructed. In 1993, an aviation fueling system was installed. In 2000, Runway 1-19 was reconstructed and repaved. In 2003, a terminal building and hangar were constructed. In 2009, the FAA approved to increase the runway width by 10 ft., and the length by 700 ft. the runway would expand to 3,206 ft. This expansion would make it possible for the airport to accommodate small jets. The State of Vermont 2007 Airport System & Policy Plan calls for ‘Local Service Airports’ (such as the Middlebury Airport) to increase their runways to 4,000 ft. length x 75 ft. width, pending appropriate land acquisitions and completion of environmental review and permitting. On June 9, 2015, the Town of Middlebury Selectboard voted in favor of a proposed $3.5m project would entail acquiring the navigation easements from property owners abutting the southern approach of the runway (for tree removal, which addresses current visibility concerns for pilots), reconstructing and extending the taxiway in 2017, and extending the runway by 700 ft. at the northern terminus in 2018. Now in 2022, the Middlebury State Airport offers a full 3200 feet of paved runway with approximately 700 feet of turf overrun, with FAA approved areas, taxiways and AWOS station on field. The state is currently seeking to get a master plan in place to allow for much needed hangars to be built to house the current waiting list.
