I agree - from the looks of the metalwork I'd say 1920's

Just a theory but maybe this bridge was relocated here in 1950 since this road only serves one house and I can't see any traces of an old roadbed in Gooogle Earth.

The lack of any portal bracing is what stands out the most to me on this one. I thought at first maybe it had been removed to improve clearance, but with enlarging the pictures it doesn't appear that there ever was any. Perhaps with the somewhat beefier trusses the designer felt okay about omitting them altogether. While not a common practice to completely leave out portal bracing, I have seen a few others like this as well. One that comes to mind was located about 20 miles from my home and has been gone for many years now.....

These are the accurate GPS coordinates:



Probably another case of DOT or national bridge inventory using outdated GPS equipment. The listed coordinates above are in the middle of a forst LOL
