Portland International Airport (PDX) has been pivotal in connecting people and driving economic growth in the region. The airport's history is a narrative of continuous expansion, agility, and transformation. Portland's first airport was on Swan Island, operating from 1927 to 1940. In 1936, the City of Portland purchased 700 acres of land along the Columbia River, and construction of the new airport began. The new Portland-Columbia Airport was completed in 1940, and it has since undergone numerous upgrades and expansions to become the thriving international gateway it is today.

Portland's first airport was Swan Island Airport, operating from 1927 to 1940
Portland's first airport was Swan Island Municipal Airport, located on an island in the Willamette River, northwest of downtown Portland. The Port of Portland purchased 256 acres of land in 1926 and construction of the airport began the same year. The airport opened for limited use on September 14, 1927, with Charles Lindbergh dedicating the new airfield by flying in the Spirit of St. Louis. The official opening ceremony took place on September 27, 1927, during the Pacific Coast Air Derby, with six army planes performing for 10,000 spectators.
The choice of Swan Island as the location for the airport was not without controversy. The island was initially a marshy, undeveloped peninsula, and concerns were raised about the potential for flooding. A major project was undertaken to dredge the Willamette River, with the spoils used to fill and level the island, increasing its size to 900 acres. A dike was also constructed to control flooding and keep high water out. Despite these efforts, the airport continued to face challenges due to its low altitude, and by the mid-1930s, it was becoming obsolete.
During its operation, Swan Island Airport played a significant role in the development of aviation in Portland. In 1929, Varney Air Lines began passenger services from the airport to Boise, Idaho, Salt Lake City, Utah, and Pasco, Washington. However, the airport's small runways and low altitude made it difficult for newer, larger aircraft to operate safely. As a result, the Portland City Council began exploring options for a new, larger airport, and in 1940, the Portland–Columbia Super Airport (now known as Portland International Airport) was completed, rendering Swan Island Airport obsolete.
Swan Island Airport ceased operations as a commercial airport in 1940, and the new airport became the primary aviation hub for Portland. During World War II, Swan Island was converted into a war production site, housing a Kaiser shipyard and worker accommodations. The shipbuilding facilities were later acquired by the Port of Portland after the war, and the island became a centre for port operations, including dry dock and ship repair services. Today, Swan Island remains an important industrial hub for distribution, warehousing, and manufacturing activities, contributing to the economic growth and development of the region.

The current site was purchased in 1936 and built with a Works Progress Administration grant
Portland, Oregon, has had two locations for its major commercial airport. The first was Swan Island Airport, which operated from 1927 until 1940. The current site of Portland International Airport was purchased in 1936 and built with a Works Progress Administration (WPA) grant.
The City of Portland bought 700 acres of land along the Columbia River in 1936. This land was marshy and required 4 million cubic yards of fill to be usable. The Portland City Council issued $300,000 and requested that the Port of Portland sponsor a $1.3 million grant from the Works Progress Administration to develop the site into a "super airport". The project provided much-needed jobs during the Great Depression, employing over 1,000 men.
The Works Progress Administration and the Port of Portland faced challenges preparing the site for construction due to frequent flooding from the Columbia River. To address this, workers covered the area with sand to aid drainage and constructed dikes to control flooding. The new Portland-Columbia Airport was completed in 1940 and had its opening ceremony on October 13. The airport included a terminal located off Marine Drive and runways forming an X toward the western side.
The Portland-Columbia Airport was designated "Portland–Columbia Airport" to distinguish it from the previously operating Swan Island Airport. During World War II, the airfield was utilised by the United States Army Air Forces. The airport underwent further expansion in the 1950s, including the construction of a new terminal and longer runways to accommodate jet aircraft.

The airport was completed in 1940 and was used by the US Army during World War II
Portland International Airport has a long and fascinating history. The airport was completed in 1940 and was used by the US Army during World War II.
The site for the airport was purchased in 1936 by the City of Portland, who bought 700 acres of land along the Columbia River. This purchase was funded by a $300,000 bond issue and a $1.3 million grant from the Works Progress Administration (WPA). The airport's construction provided much-needed jobs during the Great Depression, employing over 1,000 men. The site, which was initially a marshy floodplain, required significant work to make it usable, including covering the area with over 4 million cubic yards of sand to aid drainage.
The airport was originally known as Portland-Columbia Airport to distinguish it from the then-operating Swan Island Airport, which had opened in 1927. The new airport featured a terminal located off Marine Drive and runways forming an X or an asterisk shape. During World War II, the airfield was used by the United States Army Air Forces and served as a base for Civil Air Patrol planes searching for enemy submarines. The airport was also used for lend-lease aircraft passing through to Canada.
After World War II, the airport came under the management of the Port of Portland and was officially renamed Portland International Airport in 1948 or, according to another source, in 1951 when it began operating international flights. The airport underwent further expansion and upgrades in the 1950s, including the construction of a new terminal and longer runways to accommodate jet aircraft. This transformation continued in the 1960s and 1970s, with additional expansions and improvements to the terminal and runway facilities, solidifying its position as a significant transportation hub.
