The world's busiest airport is set to get even busier.

The federal government has awarded Hartsfield-Jackson Atlanta International Airport almost $34 million in stimulus funds to help pay for construction of a new terminal.

The Federal Aviation Administration's Airport Improvement Program granted Hartsfield-Jackson $13.97 million to build the apron for the new Maynard Holbrook Jackson Jr. International Terminal.

The Transportation Security Administration provided $20 million to develop a baggage-screening system.

Construction on the international terminal, which began in summer 2008, is expected to be completed by spring 2012. The total cost is $1.35 billion.

The 12-gate facility will connect via the automated people mover to the existing international Concourse E, creating a 40-gate international air travel complex at Hartsfield-Jackson.

Atlanta Hartsfield Jackson is the busiest airport in the world, accommodating around 90 million passengers in 2008.
