It is unclear who thinks up for horrible names for roads. The bridge itself is deserving of a name nicer than H50. This bridge is seated on attractive stone abutments which are in fairly poor condition. The bridge itself is in decent condition. There is v-lacing on the verticals, diagonals, and under the top chord and end posts. Cambria stamps are present on the steel. Lattice railings remain on the bridge. One of the unusual details of this Warren truss bridge is there is only a single vertical member on each truss, right in the center of the bridge. No other vertical members are present.
Information and Findings From Ohio's Historic Bridge Inventory
The bridge carries a 2 lane road over a stream in a rural area of active farms. There is a period farmhouse beyond one quadrant.
The 1 span, 37'-long, rivet-connected Warren pony truss bridge is traditionally composed of built-up members. It has lattice railings, concrete deck, and is supported on stone abutments.
Summary of Significance
The 1914 rivet-connected Warren pony truss bridge has no unusual or distinctive features, being a short-span example of the most common rivet-connected truss bridge type/design of the 20th century. The Ohio Phase
1A survey (2008) has identified more than 500 examples dating from 1897 to 1961, accounting for well over half of the approximately 800 pre-1961 metal trusses. The Warren design was particularly well suited to rigid (riveted, and
later welded connections), but not as well suited to pin connections; this helps to explain its popularity in the 20th century rather than the 19th century, although it is based on a British patent issued to engineers James Warren
and Willoughby Monzani in 1848. In the U.S., the popularity of the Warren truss coincided with improvements in pneumatic field riveting equipment starting about 1900. The Warren, which is based on a series of equilateral triangles,
is identified by its simplicity of design, ease of construction with equal-sized members, and ability of some diagonals to act in both tensions and compression. Warren trusses are often stiffened by the addition of verticals; they
can also have polygonal (sloped) upper chords to achieve greatest depth at midspan.
