When Denver took a whole lot of sage brush (thousands of acres) and made a airport out of it - it was a from-scratch effort.   Six levels of vehicle accesses on each side of the terminal allow busses, arriving passengers, departing passengers, service and others to use their very own level. 

 The translucent white fabric which wraps the main terminal has peaks reminiscent of the snow capped peaks on the Rocky Mountains 30 miles to the west.  (According to a local, the fabric has only ripped twice in the decade the terminal has been up – both times due to snow load)

 As you can see in the photo above, there are lots of avant-qarde solar panels strategically placed as eye candy (some are not angling correctly) right between the entrance and the exit freeways. To save conventional fossil energy?

 But, curiously, while a new freeway was built from Denver to Jeppeson, somehow light rail was forgotten.  

 I will bet that had to do with lobbying from the car rental companies.   This is a typical example of the clash between profit minded corporate America, and our weak democracy and the weaker urban planning our governments are able to muster.
