The St George airport will be closing for 4 months in 2019. Apparently there is a issue with the soil under the runway and the entire thing has to be replaced. It seems ridiculous that they can't figure out a way around shutting down the entire airport. This will surely stunt the great growth that has been happening with new flights recently.
