Description 

While visiting this bridge last summer, I noticed that there is no defined creek that passes under this bridge. There are two other bridges on this road, a concrete T-beam from the 1920's (which I have added to the website) and another steel truss bridge (which I did not know about, and therefore missed altogether). The map above shows the main channel of the Cannon River, which is spanned by the concrete bridge, and a side channel of the Cannon River, which is spanned by the steel bridge that I missed. This bridge crosses over a flood area that usually does not have any more than a few large holes filled with water. I intend to make another trip to this road after the weather warms up to visit and photograph the bridge that I missed.

Cannon Bottoms Rd bridge, south truss

It does not look like it was originally pin-connected - yet the general construction style is more typical of the earlier pin-connected than the later riveted. I see this especially at the top joints.

I have a bunch of photos of this bridge I need to edit and upload...

Thanks Tony! I guess I'm still learning the details. The age and the way the gussets were done makes it look like they were added later but, I'm still new to this.

Looks like it was built as a riveted span Art.

Something looks odd to me. Was this bridge a pin connected truss that was retrofitted with riveted connections?
