Engineering Feats > An Airport Twice the Size of Manhattan

 

This airport was the second largest public works project in the world, smaller only than the Chunnel linking England and France.  Based on land mass, it is the largest airport in the U.S. and the third largest in the world.
 
More than 110 million cubic yards of earth were moved during the construction project.  The airport has 17 mechanical rooms, 1.3 million pounds of ductwork and 39 miles of piping.  It boasts the largest jet fuel distribution system in the world. 
 
Runways are spaced at least 4,300 feet apart and meet FAA requirements for bad weather take-offs.  The airport has electric-powered subway lines capable of moving 6,000 people per hour. 
 
In 2006, the airport handled nearly 50 million passengers.   
 
What is this modern engineering marvel?

 

 

 

Construction of the Denver International Airport began in 1989.  After numerous construction delays, including problems with the airport's infamous automated baggage system, the airport was finally opened in 1995.

 

The final cost of the project was $5.2 billion, almost $2 billion over budget.  The numerous delays resulted in the airport opening running 16 months behind the original schedule.  In fact, the numerous delays earned DIA (Denver International Airport) many nicknames, including "Delayed Indefinitely Airport" and "Denver's Imaginary Airport".

 

Despite the construction delays and cost overruns, the project was an impressive engineering feat.  At the height of construction, DIA employed more than 11,000 workers.

 

The new airport allows Denver to accommodate tens of millions of passengers each year.  Unlike Stapleton, the airport that it replaced, DIA was built to handle Denver's unique weather conditions and wind patterns.  The airport's pinwheel design and location well outside the city allows for future expansion well into the 21st century and beyond.
