Here are a few major landmarks, key routes, and the like from someone that grew up and spent most my life in Utah. Some may be slightly distant from a road but should be connected. Know that Utah is well known for their mountains and national parks. Much of the state revenue is pulled from the state parks. Many cities and towns rely heavily on these parks and their tourism. So any way you can include them, within reason of course, would rely show off Utah in it's glory. I know for a fact that many ATS fans have been looking forward to some challenging routes, steep slopes, and change of scenery, so a lot of roads that go through the rocky Mountains would be key.
1) Devil's Slide

2) Garden City, UT and Bear Lake State Park
3) Salt flats (lots of movies were made in this area)
4) Moab, UT (major tourist area and is near a couple national parks including Arches that includes the State Arch "Delicate Arch" seen on signs and license plates, Not necessarily accessible for through truck traffic, but maybe some deliveries to these would be good Utah is well known for their state parks and it's where they receive much of their state revenue and thrive)
5) St. George, joins Salt Lake City as one of the oldest cities in Utah and is a gorgeous city right off of I-15.
6) Cars can drive through Zion's National Park, I doubt trucks are but if you were to put that in the game it is contains gorgeous red cliffs and green trees, waterfalls (though these I believe are far off the main road). It could be used as a means to drive through like what you did with the Yosemite National Park in California.
7) Any road going through the Rocky Mountain Range needs to show a good slope. Especially on I-80 between Salt Lake City and Park City. There's a few areas in there that are pretty steep! Still accessible by trucks but steep.
8) Park City was used during the 2002 Winter Olympic Games from the freeway (I-80) heading west you can still see the Ski Jumps (

9) Heber City, UT has an historic Railroad
10) Speaking of Railroads, Promontory Point is out of the way a bit but is a huge site for the US. It is the location where the first railroad that stretched from east coast to west coast met. In the summer time they actually reenact the two locomotives coming together. This is some history for the US not just UT.
11) Dugway, UT is in close proximity to a US Army Air base.
12) Heading east out of Orem , UT is Highway 189 or Provo Canyon Road goes through Provo Canyon which is another beautiful drive and used heavily during the fall season to see the trees as they change colors.
13) As mentioned already the Salt Lake Temple from the Church of Jesus Christ of Latter Day Saints is a landmark as are many other temples in Utah, including the St. George Temple in St. George, UT and Logan Temple in Logan, UT.

14) Logan, UT is another beautiful city that is in the mountains.
15) Vernal, UT is another beautiful city.
16) Within Salt Lake City there's several free way interchanges that would be great to see, the most well known and confusing that would be great to see in the game is the junction where I-80, I-15, and Highway 201 come together. It's a tall and iconic engineering structure in Salt Lake City
17) Since you have Arizona, New Mexico, and, with this research, Utah, you can successfully do "Four Corners" it's a historical site at the border of Arizona, New Mexico, Utah, and Colorado with a little plaque and lines painted on the ground showing the borders. It's the only location in the United states where four states come together at a their corners.

18) There is an island within the Great Salt Lake that has a road leading to it. The island is a state park and has no services, but it would be pretty neat to have something like that in the game. Also something to be of note, the Great Salt Lake is farmed for salt, there are industries on the south side of the lake along I-80 that facilitate in the farming.
19) I can't believe I almost forgot this one and it would be great for Special Transport, Heavy Haul, and general industries. Probably an absolute must. The Kennecott Copper Mine is a large active mind, said to be seen from space, using heavy machinary to mine copper, gold, silver, molybdenum.

As for roads, here are some key major roads to help in your selection/research as well (starting with the obvious):
1) I-15
2) I-80
3) I-84
4) I-70
5) Highway 50
6) Highway 191 (from Vernal to Bluff)
7) Highway 9
8) Highway 189
9) Highway 40
10) Highway 30
11) Highway 89
12) Highway 191 would be a good one as well. This route takes you to many of the popular ski slopes that could be used for deliveries and possibly a back route from Salt Lake City to Heber City and Park City. This would be a great one that would provide some challenge going through the mountains off of a freeway which tend to have less switchbacks. The highway that goes through that point goes through the others states (not Utah) but one to keep in if not for Utah, then for Colorado when it comes around.
Key Cities to think about and provide variety to the Utah landscape:
1) Salt Lake City
2) Orem/Provo
3) Ogden
4) Logan
5) Garden City
6) Park City
7) Vernal
8) Heber
9) Dugway or Delta separate but similar landscape
10) Tooele/Granstville
11) Echo/Coalville
12) Green River
13) Moab
14) Filmore
15) Beaver
16) Cedar City
17) Orderville or Kanab are well known and visited small towns.
19) Monticello
That's pretty much it, trying to keep it short but broad so you have lots to go off of and help make decisions easier.
