Interesting fact: Airports include vast areas of paved runways, terminals, hangars, and other infrastructure, making their total weight extremely large and complex to estimate.
The answer: A large international airport's built structures and paved surfaces can weigh several million metric tons, often exceeding 5 million metric tons (over 11 billion pounds) when including runways, terminals, and support buildings.
Airports are sprawling complexes with extensive infrastructure including runways, taxiways, terminals, parking garages, and maintenance facilities. The weight includes concrete and asphalt pavements, steel and concrete buildings, and equipment. For example, the paved surfaces alone at a major airport like Los Angeles International Airport cover thousands of acres and contribute significantly to the total weight. Estimating an airport's weight involves considering all constructed elements, making it one of the heaviest man-made structures on Earth.
