Honestly Robert... The surprise for me would come if Tennessee decided to SAVE an historic truss bridge! :-(
Surprisingly, this bridge appears to be doomed:

I have driven across it in previous years, but the road was closed when I was in the area a few days ago.
This bridge is, or perhaps was, located in a National Wildlife Refuge and was just downstream from a modern four lane concrete bridge that carries Interstate 40. I figured the Tennessee would preserve this one but apparently no such luck. It primarily carried local traffic and visitors to the Wildlife Refuge.
I just noticed that this bridge is an almost identical twin to the one on Highway 104 over the Obion River in Dyer County, built just the year prior: http://bridgehunter.com/tn/dyer/23SR0200009/
The deck width and main span length are identical, and the structures are almost identical, right down to the side rails. (I have noticed some very minor differences in the pieces used on some of the bracing up top and the X in the middle panel of the truss.) The vertical clearances listed on this site for the two are about seven inches apart from one another, but I'll measure them in the field first-hand next time I'm out to see if that's the case.
I wonder if the manufacturer is the same. The plaque on the bridge over the Obion lists Virginia Bridge and Iron Co. of Roanoke, Va. I've never looked at the plaque on the one over the Hatchie the few times I've been across it. I seem to always pass through there at night or during bad weather.
I personally visited this bridge to photograph the steel truss on January16, 2020 and found it gone. Its replacement is a "prestressed concrete stringer" (i.e. boring) bridge. RIP, my friend.
