I'm planning a road trip from Seattle to Flagstaff, AZ in September via eastern WA - NE Oregon - S Idaho, then a straight shot south through Utah into Arizona on SR 89.
I've heard reports that driving through the SLC area at any time of the day is just ugly - horrid traffic and incessant construction. One friend said he'd rather drive thru Los Angeles, a strong statement. He suggested heading S at Twin Falls, ID and dropping thru Nevada and Vegas to get to Arizona. I'm not excited by the prospect of driving thru Nevada.
Thought I might avoid traffic ugliness around SLC by heading eastward just past Ogden and looping around Rt 84 thru Morgan, Coalville, then down thru Heber City, linking up again with the main route south again, at Provo.
Can anyone share experiences with these routes? I've never been to the SW before, and would like to get to Flagstaff by the shortest/fastest possible route. Thanks
