Just outside off Manhattan off K18. Depending where you are in St. George and traffic, should be no more then 20-25 minutes ma'am.
St George is about 18miles from the airport on the east side of Manhattan on US-24. You can drive it in about 25 minutes!
I live one mile north of Green Valley road and US-24. It takes me 17-20 minutes depending on traffic. I drive it regularly almost weekly.
