A non-technical term I like to use for this type of structure is "Womper-Jawed".
Neither have I....crazy/cool engineering
Thanks Nathan. I have just not encountered many Pratts that looked like this.
Royce
Unless I am missing something, no there is not, aside from describing its unusual design features of vertical end posts and a heavy skew, but these don't play into the type of truss configuration here. Its basically a Pratt truss with a skew and vertical endposts.
Is there a sub category of Pratt for this bridge?
Royce
This bridge was the old Virginian (electrified) route crossing the Norfolk and Western mainline west of Salem.

My father was a CE with the KS highway Dept ca 1950 and the term he used was "catiwhompus". I haven't run across the exact definition in any of his old books yet.
