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?

They are labeled accordingly in the HAER drawings.
Indeed they are ;-)
Is the 'tubular arch' composed of Phoenix Columns?

That makes sense.
