5 of the Most Expensive Airports Ever Built

Denver International Airport opened in 1995 after years of delays, which contributed to its exorbitant $4.8 billion price tag — around $2 billion over budget.

In the end, DIA — as it's nicknamed — totaled $3 billion in construction costs alone, plus $1.8 billion in related projects (equivalent to about $9 billion total today). DIA's high price tag was due in part to the project's overall complexity, which included six underground tunnels and the Jeppesen Terminal, with its intricate roof resembling the snow-capped peaks of the Rockies. The airport — built to replace Denver's Stapleton Airport, which had run out of room to expand — was also expensive because of its sheer size. It covers 53 square miles of land, making it the largest airport in the U.S. by total land area — larger than the city of Boston, Miami, or San Francisco.
