Money, don't forget US93 Alternate splits off about 45 miles north of Ely and goes to West Wendover and the Supercharger there for those who are heading to SLC or thereabouts.
Yes - Alt 93 is an important corridor. The history is interesting.
Historically, the original 1913 alignment of the Lincoln Highway went westward from SLC down what is now Skull Valley Road in Western Utah to what is now Dugway, then picked up the old Pony Express trail across the rest of Utah (e.g., Fish Springs, Callao, Ibapah, etc) and into Nevada. Once westbound travelers reached Ely, those headed towards San Francisco headed west - again more or less on the Pony Express trail and todays US 50. Those headed towards Los Angeles took the more southwestern route.
In about 1919-1920, the State of Utah decided they wanted to keep Los Angeles-bound travelers inside Utah - to the advantage of businesses (e.g., inns, gas stations, diners, etc) along the route. So they renigged on building some improvements between Dugway and Gold Hill (the so-called Goodyear Cutoff) that the Lincoln Highway Association had raised funds for, combined with some Federal funds, and used them elsewhere. Thus creating the corridor that is now I-15 towards Las Vegas. They also took a few years to build the road across the marsh lands on the south side of Salt Lake to Wendover - basically what is now I-80. Nevada then built what is now Alt 93 to 93, and on to McGill and Ely. The original 1913 LH alignment between Dugway and 93 is still mostly gravel and dirt to this day. Portions of it, and almost all of the Goodyear Cutoff, are now inside the Dugway Proving Grounds and off limits to the general public.
From Ely westward, the LH again followed the old Pony Express trail all the way to Carson City and beyond - more or less along todays US 50. Though when one reached Fallon, there was an alternate route to Reno and over Donner Pass.
