Grand Ridge Road Bridge
Time isn't helping this bridge any. You can tell the 6 years difference between photos.
Grand Ridge Road Bridge
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.

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.
