Can confirm.
When I visited a client in Arkansas, I had a chance to see this aamaaaazing moving sidewalk. In fact, it had a sign that the endless sidewalk (as far as the eye could see) was the longest in Arkansas. Well, apparently its the only one... and the staggering length will mystify you (that's what she said)

The 55-foot moving sidewalk in the concourse takes up a lot of space and is regularly inoperable or in need of repair, according to airport staff. An evaluation found the moving sidewalk isn't needed to meet Americans with Disabilities Act requirements and actually poses liability issues.
The moving sidewalk was billed as the first in Arkansas when it was installed more than a decade ago. The walkway has its own Facebook page: "The Only Moving Walkway in the State of Arkansas."
