The airport's most expensive art project ever produced has gone through a series of twists, turns and delays since it was first selected for the space.
It was originally expected to be completed in 2004 but was postponed amid economic challenges. The budget ballooned from $1.3 million more than a decade ago to a total of $4.1 million, including $2 million for electrical work. Materials for the piece had to be redesigned to comply with current safety codes, and the price increased because of rising labor and material costs, including a conversion from neon to more energy-efficient LED lighting.
Atlanta's public art master plan calls for setting aside 1 percent of certain spending for art, and the airport has said the installation is paid for with funds set aside from airport-associated fees, such as lease payments by airlines and parking revenue.
Flight Paths is part of a series of installations in the underground tunnels at Hartsfield-Jackson, including the "Tradition in Stone" exhibit of stone sculptures from Zimbabwe between Concourses T and A, and "A Walk Through Atlanta History" between Concourses B and C.
