Did Denver International Airport confirm its conspiracy theories?

(Denver, Colo) Since opening in 1995, plenty of conspiracy theories have cropped up about Denver International Airport — from the idea that there are underground bunkers built for a secret society to the notion that the blue mustang with beady red eyes is cursed.

So, to poke fun at its legacy of conspiracy theories, DIA has turned the rumors into the theme of its cheeky construction signs. The conspiracy-laden signs might surprise travelers passing through Denver, but it feels like an inside joke for people who live in the Mile High City.

DIA, among the world’s busiest airports, has been under construction since 2018. The airport warns travelers projects will continue e through at least spring 2027.

The rotation of construction signs has acknowledged theories ranging from the airport being home to a mysterious colony of lizard people to the belief that artwork contains apocalyptic clues. Another rumor pinpoints the airport as the Illuminati's headquarters.

When it comes to conspiracy theories, DIA is self-aware. One of the newest construction signs by a security entrance says: “Forgive the mess. Building secret underground tunnels can get quite untidy.” Another says: "Apologies for the noise. It takes really big drills to get to the underworld."

The airport’s Jeppesen Terminal was initially built to accommodate 50 million passengers per year, but officials say they expect 70 million passengers to travel through DIA in 2022, and that number will grow to 100 million annually in the next decade. Denver added additional gates to keep up with the growth, and three dozen new restaurants will land at DIA in the next couple of years.

The first two phases of the airport’s Great Hall project will cost $770 million. Construction started slowly, with project delays and the city firing the original contractor. Now, the airport has moved to its $1.3 billion completion phase.

While the airport previously used signs to tease its expanding bunkers, revamping lizards’ lairs and giving the glaring gargoyles a makeover, the project focuses on streamlined security checkpoints, modern ticketing spaces and adding more restaurants and bars.
