Phoenix to Salt Lake City is about 660 miles, 10-11 hours drive β typically a two-day move with an overnight in Saint George or Cedar City. The route is straightforward: I-17 north to Flagstaff, US-89 north to Page, then north on US-89 and US-89A through Kanab to I-15.
We see steady traffic both directions β Phoenix to SLC for jobs (tech industry growing rapidly along the Wasatch Front), SLC to Phoenix for retirement and weather. A handful of LDS family moves either direction (extended family relocating to be near each other).
BBB A+
