A Queenpost would have an upper chord of at least one panel, that is parallel to the lower chord.
The use of rods for the tensile members in both Kings and Queens is found both in roof (more of these survive into the present day) and bridge trusses and is / was not the least bit uncommon. Foundry's were spitting out rods and Angle Blocks, and / or Angle Washers for both for short span trusses from the '70's through the aught's at least
A center single panel point, (even if it is a double rod setup) and the absence of a Straining Beam quite clearly make this a King.
I do not know the difference between queen and king and when i look it up it seems like they are interchangeable. I need help with these bridges.
Anyone think this is actually a kingpost rather than queen?
HISTORIQUE/NON MODERNE - I thinque :-)
Hard to tell for sure from the photos, but they look old. The railing posts look ornate. The use of rods for the vertical does not have the appearance of a modern bridge to me.
Just added this and its sister bridge (http://bridgehunter.com/il/peoria/black/). I'm wondering if these bridges are authentic trusses or if they are just "modern prefabs" placed in the cemetery for decorative purposes. Anyway, if someone can give tell either way and give more info on the kind of design, since I am not really familiar with this kind of truss, please do so.
