The 68-year-old singer said it was the right time to hit the road.
"It has to be now," she said. "I can still do it. (I'm) still in shape enough physically, mentally and I think this was about the best time to do it."
Turner performed fan favorites such as "Typical Male," "What's Love Got to Do With It?" and "Private Dancer."
An entertainer for 50 years, Turner said she can "still give a great show," adding that her longevity inspires fans of all ages.
"Why I dance at such a pace is because it feels good with the dance and I'm known for that kind of energy," she said. "Young kids can really relate to that as well. So I think that my (fans') age group ranges from young to old, to my age, because of the energy projected from the stage."
