Mark Road Bridge
Why it's listed
Mark Road Bridge is a 103-foot, single-span Pratt through truss that carries a township road over Sugar Creek in southern Fayette County, Ohio. The Wrought Iron Bridge Company of Canton built it in 1883, and cast-iron plates on the portals name the firm, the date, and the three county commissioners. The bridge has seven panels, pin connections, eyebar tension members, and a wooden floor. Its limestone abutments remain, though one wingwall has been capped with concrete and reinforced with steel piling. The bridge was listed for its engineering value. Pin-connected metal trusses were the most common highway bridge type of the 1880s, allowing parts to be mass-produced and quickly assembled by unskilled labor. The Canton firm was among Ohio's largest, and this bridge uses channel beams based on an 1876 patent by company founder David Hammond. Only a handful of such wrought-iron Pratt trusses survive in Ohio, and this is one of two known rural examples from the 1880s.
Significance in brief: The bridge is significant under Criterion C in engineering as an example of the metal through-truss, the main highway bridge design in Ohio and the nation in the late nineteenth and early twentieth centuries. It also represents the work of the Wrought Iron Bridge Company, one of the largest bridge firms of its day. It is believed to be one of only two surviving Ohio examples of the firm's rural highway bridges from the 1880s.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
