PANDORA — The Putnam County Commissioners have approved applying for a
grant to do major repairs to a bridge of historical significance in
Putnam County. Known as the Mallaham Bridge, the bridge goes over Riley
Creek on M6, northwest of Pandora.
Built in 1876 by D.H. Morrison,
the bridge is listed in the Historic American Engineer Record as an
example of “Morrison’s Patent Wrought Iron Arch Truss Bridge,” based on a
patent granted David H. Morrison. Unique among bowstring arches, this
designed used vertically-oriented I-Beam flanges to form the bows.
Morrison, founder of the Columbus Bridge Works in Dayton, was one of the
most important bridge engineers and manufacturers in the 19th century
The United States Congress has set aside monies for
Transportation Enhancement projects through the State of Ohio Department
of Transportation. The commissioners are applying for money from this
fund. The total construction cost of the M6 bridge project is estimated
to be $386,000 of which the county would commit to pay at least 20
percent ($77,200 estimate) of the actual construction cost.
Putnam County Engineers office’s Troy Recker said the application was
filed this week. He expects to hear if the county received it sometime
The county would also be responsible for 100 percent of
all other costs associated with the architectural/engineering plans,
environmental studies and documentation, right-of-way plans and
right-of-way acquisition, if necessary. The local portion would be
funded by the county using Emergency Bridge Fund money.
said the construction will include taking the bridge apart, cleaning and
galvanizing it and reassembling it to maintain the historical
significance of the arches and beams of the bridge. The county would
also do work on the approaches to the bridge.
Although not listed
on the National Register for Historic Places, the bridge, has been
considered eligible for this status. The bridge is approximately 16.1
feet wide and 86 feet long. The length of the largest span is 80.1 feet.
