Great news Scott! I'm glad to see they aren't going to abandon it like they did with Butler and Lost Bridges.

I copied your pic to the main page.

I spent most of my Saturday morning exploring the Iron Bridges of Miami county. This bridge seemed to be in the best shape of the lot. I have attached a few photos taken 2-27-10 after a fresh snowfall.

Drove over the bridge last weekend (May 24, 2009)and noticed all the bad boards have been replaced on the decking. It was nice to see. Supposedly they want to build a new bridge downstream at some point, but this bridge will remain, probably blocked off with pedestrian access only I would presume. I imagine this won't happen until the economy picks back up.

I used to live on 440 West at 350 North and the bridge was a half mile away(Straightline GPS). I could hear the boards rattling on the North span in my living room with the tv on and the doors and windows closed everytime a vehicle crossed! Indeed loud. Still scary when I would see one of the county's dump trucks cross. I believe if it wasn't for the "Iron Bridges Festival" in Miami County started a few years ago, this bridge would be closed. I remember several years before the festival was around when they had replaced the deck, the comment was made that this would be the last time. Not long after, the holes returned(thanks arsonist's) and the street signs were put in to patch it. It was at least partially redecked last year(2006) according to my cousin who still lives in the old house. Great place for Canoe trip launches, as many have used this spot for years for this and easily accessible fishing areas. I was suprized when the bridge survived horrible flooding in the late 1990's that had water within a foot of the decking supports. I have seen the limestone block piers survive bad ice gorges as well thanks to the iron mounted on the upstream side of the piers. Quite a bridge!

Here are a few more pictures of Denniston Bridge. The photo of the plaque isnít very good, but reads Built By Massillon Bridge Co. 1884.

The last picture is the floor from underneath, As you can see from the deck photos there are old road signs nailed to the deck. These are patches for some rather large holes in the floor. Makes driving over it just a little more scary!

Webmaster's note: The photos that were here have been incorporated into the main site.
