Atlanta int'l airport isn't the only one, Seattle-Tacoma Int'l Airport is in expansion for a 3rd runaway and expanding their new terminal, many airports around the states are going for that also. The price tag for the 3rd runaway at Sea-Tac airport is $1.2 billion. *whoa* They recently added a new 250 ft tall
tower for flight traffic control 2 years ago, the old one is short.
