Post #19 looks like the interstate 70 bridge as it crosses the Missouri River. Which, by the way is quite high right now from all the rain we have been having.
SH70, nearing the Panhandle 20 miles outside Truth or Consequences, NM It's a bit taller'n that, but still Approaching the Moki Dugway, Utah Artist's Palette, Death Valley Highway 6 out of Tonopah, Nevada Highway 50, somewhere in Colorado
Quite possible...I took 50 from Grand Junction to Pueblo. It was white-knuckle for me in the Rockies...I can't stand heights.
