Portland International Jetport: A Century of Evolution from Biplane Field to Regional Hub
In short: Portland International Jetport, known as PWM, serves as a vital multi-use facility for Maine. While it handles everything from light general aviation to heavy military aircraft, its history reveals a transformation from a small private airfield for biplanes into the state's busiest passenger gateway, shaped by decades of infrastructure expansion.
The airport originated in the late 1920s when Dr. Clifford Strange required a space for his JN-4 Jenny biplane. Known initially as Stroudwater Airport, it began commercial operations in 1931 with Boston-Maine Airways. By 1937, the City of Portland purchased the site for $68,471, renaming it Portland-Westbrook Municipal Airport. This name is the source of the airport's current code, PWM, which references a directional light in the neighboring city of Westbrook.
During the 1930s, the facility underwent significant development through federal New Deal programs. Between 1934 and 1935, the Maine Emergency Relief Administration spent over $800,000 on labor for airport construction, including the creation of two gravel runways. The Works Progress Administration later constructed the airport's first permanent brick terminal in 1940. Following the Second World War, the airport configuration evolved significantly, with the current runway 11-29 system established in 1957 and later lengthened to 6,800 feet in 1966.
Today, the Jetport is a complex, multi-use environment managed by the City of Portland. Its current configuration features two intersecting runways, 11-29 and 18-36, supported by a parallel taxiway system that provides access to terminals and parking ramps. The airport has seen record-breaking traffic, handling approximately 2.44 million passengers in 2024. Recent infrastructure efforts, such as taxiway lighting upgrades and federal funding for new taxiway connections, ensure the facility remains a critical component of the National Airspace System, supporting both commercial air carriers and general aviation needs.
