Design
"Cooper's Tubular Arch Bridge was built in 1886 for the Town of Canajoharie, New York by Melvin A. Nash, a Fort Edward, New York bridge builder. It is the only extant example of superstructure fabricated on the 1873 patent of civil engineer William B. Cooper, then employed on the New York State Canals. In 1975, the bridge was acquired by the Central New York State Park and Recreation Commission and moved to the Old Erie Canal State Park in De Witt, where it now carries pedestrians and service vehicles across a restored portion of the original canal. ... His [Cooper's] design was one of a variety of trusses of the bowstring and tied arch forms widely used for small highway and street crossings during the mid-to-late nineteenth century. The configuration of its trusses places it in a direct line of descendance from the arched trusses of New York engineer and inventor Squire Whipple, whose design was used for many years as a canal standard.."
"Cooper's Tubular Arch Bridge consists of a pair of unbraced, cast- and wrought-iron bowstring trusses seated on reinforced concrete abutments faced with coarse ashlar limestone. The bridge's superstructure is 61'-9" in overall length with a clear span of approximately 59', measured between abutment faces at the seats. The deck is approximately 16' above the water and 9-1/2' above the single towpath that parallels the canal's north bank."

That makes sense.

Yeah it just depends on what you consider a "Phoenix Column." But whatever definition you choose, the Independence bowstring is made of Phoenix's "Column segments" which are the patented rolled structural iron.

Also, the Independence Bowstring Bridge in Kansas used Phoenix Columns for the main span and Keystone columns for the approach span.

Note that the Phoenix columns on the main span of the Independence Bowstring Bridge have flattened sections added to them. KSHS still considers them to be Phoenix columns, which makes good sense.

The Henszey bowstrings use rolled Phoenix or Phoenix style sections, but were not used to form a whole column.

Other than that off the top of my head the couple WIBC bowstrings that used Phoenix columns instead of the usual columns they used that are similar to Keystone columns.

Nathan,

This design uses relatively short but straight Phoenix Column sections mimicking the cast sections of the original Whipple patent.

Wrought Iron Bridge Co. actually bent (or had Phoenix bend) the columns, with and without extra sections in the columns (round and non-round columns).

Are there other Phoenix Column bowstring designs out there?

Regards,

Art S.

They are labeled accordingly in the HAER drawings.

Indeed they are ;-)

Is the 'tubular arch' composed of Phoenix Columns?
