NASHVILLE (AP) — Nashville International Airport will split into two terminals while it enters an extended phase of construction.

The airport will operate as North and South terminals starting Tuesday, when construction will begin on an expansion of the central lobby, according to a news release.

Once past the new security checkpoints for North and South terminals, getting from Concourses A/B to C/D will require exiting and going through security again.

Once construction finishes in 2023, the expanded lobby will include a bigger central security checkpoint, a new concessions marketplace, a pedestrian bridge connecting to a terminal garage, a new International Arrivals Facility and a new look.
