The world's busiest airport in Atlanta plans to close one of its three checkpoints in the domestic terminal for three weeks.

Hartsfield-Jackson Atlanta International Airport officials said the plan is to close the south security checkpoint beginning Wednesday night to install new automated screening equipment.

Airport officials say the Transportation Security Administration will open more security lanes in the other two domestic screening areas: the main checkpoint and the north checkpoint. Airport officials said the TSA will deploy personnel to the other two checkpoints during the closure.

Airport officials say the new equipment is aimed at enhancing security with "reasonable" wait times for passengers.

The airport's general manager, Miguel Southwell, said in March that improving wait times for passenger screenings would be a key goal in 2016.
