Description 

A one-span, pinned Pratt through truss, with top chords and end post channels with lacing on the top and bottom. The bottom chords, which are below the floor beam, are paired rectilinear eyebards. Verticals are channels with lacing, except the hip verticals, which are paired rectilinear eyebards, as are the diagonals. The counters are paired rectilinear tie rods. The truss is resting on masonry abutments, probably erected in 1889 with concrete caps probably added in 1909 (the last known improvements).

I hadn't noticed this beauty before... Not sure how safe it is in Tennessee!
