It is a good road. Yes two lanes the whole way. Easy grade as you head into Ely. Always seems cooler than I expect. People seem to be good about passing and very light traffic. Watch your fuel as there are a couple spots 100 miles between stations.
+1 for the 318 short cut. There are a few small towns to respect the speed limit. We are on this road about every year. Have been around to the east and west and this 93 is the best.
There is a decent GoodSam campground called Valley View just north of Ely if you want to break the journey into two days.
