Description 

Technical name is a pin-connected Baltimore Petit through truss, built with 2 pin-connected Pratt half-hip pony trusses on either end (both removed in 1987). The top chords and end posts are channels with lacing. The verticals are small channels with lacing, except the hip verticals and the half verticals from the midpoiint to the bottom chord that are paired with rectilinear eyerods. The bottom floor beams are "V" chevron-shaped, common in early bridges but phased out by the 1890's. This may have been one of the last vehicular Baltimore Petit's, with the chevron-shaped floor beams, rendering it historic indeed. The original masonry abutments were later repaired and strengthened with concrete. The historical marker is incorrect; although this is the only vehicular Baltimore (Petit) truss bridge in Tennessee, one other Baltimore truss bridge is still in use in Cocke County on the Norfolk-Southern Railroad crossing the French Broad River. Those are the only two Baltimore (Petit) through truss bridges in Tennessee.
