Drive, Salt Lake City
The streets are quite wide. When Brigham Young had them laid out, he specified that they should be 132 feet wide so that a team of four oxen pulling a wagon could make a U-turn.
According to Frommer's
A more tantalizing tale has it that the streets were made wide enough for polygamist Young and all his wives to walk comfortably down the street arm-in-arm, with no one forced into the gutter.
Sounds like an urban legend to me. For one thing I bet the wives would have had to be taking care of various children.
The first thing you notice when driving around the western US is how little traffic there is. In a place where you need a car to get anywhere, there surprisingly aren't many of them on the road. I guess that's due to how few people live out here. The bottom line is you are in car country and getting around generally involves driving. We were on a six-month camping trip around the US and a car was the only thing that made sense, enabling us to carry all the gear we needed for our various endeavors.
The trip from Jackson, WY to Salt Lake City, UT is about 270 miles down Route 89 and takes a little over 6 hours to drive. Montpelier, ID is about the midway point and the Huckleberry House is a nice place to break your journey.
From Salt Lake City, we would drive over 500 miles in about 8 hours to Rocky Mountain National Park in Colorado though we spent a night near Cheyenne, WY so we could do a little shopping in the Sierra Trading Post outlet there!
The drive along the edge of the Wasatch Mountains overlooking the Great Salt Lake was the highlight of my visit to Utah. The twisty mountain roads, views of the lake and the city, quiet stretches of forest with few other people all couldn't be beat.
Coming from the East, one fo the most interesting ways to go is by car or motor home, through Nebraska and Wyoming along the route of the Oregon and Mormon Trails. There you can get some idea of what early American pioneers went through, both the ones who stopped in Utah and the ones who continued to California and Oregon.
SLC handles cars very well. Downtown, the streets were built wide enough for a wagon to turn around on them, so there is a fair amount of on-street and reasonably-priced ramp parking. The downtown area, including Temple Square, the Tabernacle, and the museums and Family History Center, can be covered on foot.
By car, driving in from the east, going west into Salt lake City on I80...it is the best view of the Salt Lake Valley. You curve around all these mountains & then turn a corner & all of a sudden there it is!! Salt Lake City!! It is especially beautiful in the evening.
