Narrative Description main span number: 2 main span length: 100.0 structure length: 207.0 roadway width: 29.7 structure width: 27.0 Waltz Road passes over the Huron River just south of the small community of New Boston, near the southwest corner of Wayne COunty. The Huron River is edged by woods. The land to the south is marshy. The Waltz Road Bridge skewed, with the centerline oriented north-south. The bridge consists of two identical steel, 100-foot, 7-panel, camelback Pratt pony truss spans. The trusses are comprised of the following members: upper chord: built-up channel beam tied with X-lacing; lower chord: channel; verticals: built-up I-beam; diagonals: paired angles tied with V-lacing; floor beam: built-up I-beam; bottom lateral: paired angles. Sidewalks supported by metal brackets are attached outside of the truss on each side. Railings are angles with bar spindles; solid concrete parapets edge the approaches.
Statement of Significance The Waltz Road Bridge was one of the 15 bridges constructed by Wayne County during the road commission's 1924-1925 fiscal year. THe bridge was built at the same time that the county paved a 3.5 mile section of Waltz Road between Willow Road and New Boston. The road commission's annual report noted that grading and construction of drainage structures on the section were finished in 1924, "as also was the acquisition of 1 mile of new bridge "because of the prohibitive cost" and "the light volume of traffic involved." A temporary pedestrian bridge, however, was built for the benefit of local school children. A bridge plate, which is no longer extant, identified the builder of the superstructure as the Mt. Vernon Bridge Company of Mt. Vernon, Ohio, and credited Swingle & Robinson, contractors from Wyandotte, Michigan, with the substructure. THe newly completed span, which cost approximately $65,500, was pictured in the road commission's 1924-1925 annual report. THe oblique elevation view, shot from below the level of the deck, highlighted "the massive steel and concrete work." The design was soon tested, when a dam upstream at French Landing failed and caused the river to flood. The structure easily withstood the onslaught. Railings over the abutments were originally concrete balustrades with urn-shaped spindles. Although these railings are no longer extant, the bridge otherwise retains very good integrity and is an excellent example of 1920s pony truss construction. It is eligible for the National Register under Criterion C.
