I did a site visit for this bridge and I am very certain it is older than 1910. It could be from the late 1880s. Looks wrought iron has old style carnegie brands and fishbelly floor beams.
Time isn't helping this bridge any. You can tell the 6 years difference between photos.
I have launched my kayak many times from the spot where the overview photo was taken. The Mazon is a great river to paddle.
There is another bridge like this one about 15 miles upstream on the West Fork. It is also closed.
