Significance: Fabricated and erected in 1911, the Waverly Junction Bridge (called locally Dix's Bridge) ranks among Iowa's earliest rigid-connected highway trusses. The structure's concrete-filled steel cylinder piers, curved portal knee braces, and threaded-rod lateral bracing are typical features of pinned trusses generally built prior to 1910. The composition of the bridge's web members, their connecting gusset plates and the method of field-bolting, on the other hand, are representative of early rigid-connected trusses. These features distinguish the Waverly Junction Bridge as a transitional between the two technologies: a significant and uncommon structure in Iowa's bridge building history.
