Bridge was removed ~2003 from Adams County CR 1800N/CR 725E by Adams County Road Dept. It originally spanned Frazier creek on a little used dirt road. The original location was approx 1 mile north & west of the US24/IL96 jct between Quincy & Ursa, IL. Adams Road Dept was going to scrap this structure but discovered it to be NHRP registered; instead it was offered to the Adams County Olde Tyme Assn and moved to the Adams County Fairgrounds. During a recent deep cold snap (winter 2013-14) a structural member froze and broke. The OTA jacked it up and supported it until some future point when it might be repaired. At present there is no budget $$ for that.

Webmaster's Note: Previous location of bridge was at coordinates 40.02217, -91.37202.

Adams County Fairgrounds Mystery Pony Bridge

Glad you were able to visit the bridge and find out what is there. Its a nice historic riveted Warren pony, but not the Truesdell. Were you able, during your visit, to confirm if there were any other bridges in the fairgrounds?

Not a Truesdell but actually a Warren Pony truss. Have contacted Old Tyme Fair Assn for more info on the identity of this bridge. Stay tuned.

I followed up on Nathan's post and have posted photographic details of the bridge visible on Google imagery. I have emailed Nathan, hoping he will confirm/deny his opinion. Hopefully, this is what he suspects it to be; that would be pretty exciting for all of us bridge hunters.......

There reportedly may be a Truesdell Truss in the Adams County Fairground associated with the Adams County Old Tyme Association. If I find out more, I will let everyone know. Currently, only one Truesdell Truss is confirmed, and that is in New Hampshire. The discovery of a second one would be very exciting!

This entry represents the only bridge-like structure I can see in available imagery at the fairgrounds. It may be the Truesdell Truss, some other historic pony truss, or not a bridge at all. But it looks like some sort of pony truss to me.
