Complete Guide To Ironman 70.3 2025 Road Closures In Southern Utah

The worst traffic day in St. George, Utah is quickly approaching with the 2025 Ironman 70.3 triathlon.  

Every year, several parts of the city and surrounding smaller cities deal with road closures, heavy traffic, and detours in May. That’s because thousands travel to St. George to view, compete or volunteer for the Ironman.  

Though it is a great event for the city, locals will have a hard time navigating their way through local roads. The best thing you can do is stay home if you aren’t involved in the race on May 10.
