I understand the order of replacement. Douglas has nice shots of the Bollman with both the Whipples and Howes. I added a shot of the Bollman with the Howes. My question is: The Howes lasted 9 years; were the compression members made of cast iron or wood? My guess is painted wood but I have no evidence to support this.

Sincerely,

Art S.

The book in the sources section, where the dates came from, lists several different build dates, including 1898, which is what the cutout actually reads.

Not true on build dates. Photo shows bridge on right with portal that says 1896
