A key reason the project is expected to take so long is that the airport must keep parking available while it demolishes each deck and rebuilds at the same site.
“That’s a huge challenge,” said David Pino, Hartsfield-Jackson’s development program director of project management.
To provide parking during the work, the airport plans to build a third parking deck next to the Georgia International Convention Center to accommodate about 6,000 cars. People using that deck will have to take the existing SkyTrain people-mover to get from that parking structure to the terminal.
“People won’t be impacted until the fall of 2017,” McCranie said. “We will have a replacement deck in place once we start construction and replacement of the parking structures.”
The new decks will rise to eight levels, up from four now, with 15,000 spaces on the Terminal North side and 17,000 parking spaces on the Terminal South side after completion. Pedestrian bridges will be built from level four, according to plans.
The airport now has a total of 29,000 public spaces, including long-term lots and other non-garage spaces.
Parking is a top source of revenue for the airport, which faces competition from numerous off-site lots.
