This bridge is a good example of a standard plan rural truss bridge in Iowa with the unusual detail that all field-placed fasteners appear to be bolts instead of rivets. The shop-placed fasteners are all rivets. The bridge has a 1974 rehabilitation date listed, so it is assumed that these bolts represent an alteration dating to that time. However, if it could be proved that these bolts were not an alteration, the bridge would be significant as an early example of a truss bridge with bolted connections.
The truss is configured as follows: End post and top chord: back-to-back channels with v-lacing and cover plate. Bottom chord: outermost panels: two angles with battens, innermost panels: two paired angles with battens. Vertical members: back-to-back channels with v-lacing on each side. V-lacing is positioned parallel to the truss web. Diagonal members: two angles with battens. Portal bracing: Two paired angles with paired angles following a v-lacing pattern between. Sway bracing: upper beam: two paired angles with v-lacing, lower beam: paired angles, both beams connected by angles arranged in a double x/lattice pattern. Lateral (diagonal) bracing: single angles. Railing: two angles. Deck: Reinforced concrete surface with concrete curb and steel stringers. Floorbeams: rolled American Standard I-Beams.
