I learned of this bridge by an advertisement in the Hannibal Courier-Post, offering the bridge to any organizations interested in moving and preserving it. Sadly, the right parties were not aware of this at that time. Beautiful Bridge.

I recently discovered a few more photos of Conboy that I took in 2006. I hope to scan them soon & upload them.

I took pictures of this wonderful old bridge Summer 2006. Had planned to come back for more detailed ones but alas, I was unable to. This bridge was called Conboy Bridge, for a nearby landowner at the time it was built. I have a little history but it is at home. I will post picture(s) and info in a few days. I am an editor so I will update all of this then. Stay Tuned......

This bridge was replaced this fall by Bleigh Construction of Hannibal MO. We live near by and have some side railing as a souvenir. I have several photos during the process of tearing down and rebuilding. We loved the old bridge and was very sad in it's dismantle.

Does anyone know the current status of this bridge? If it is still available, I would like to see confirmation that it is truly a Pan American bridge co. product. I am from New Castle, In. and a local group is looking for a New Castle made bridge to move. Any info or pix of bridge would be helpful. Thank you.
