The Freedom Bridge is dismantled and stored somewhere on the park property. I'm not sure what the timeline is for rebuilding it, hopefully soon! The other bridge you mentioned is the Secrest Ferry Bridge and it is to be restored for trail use. It is actually the longest Pennsylvania Thru truss remaining that was built for road use @ 316'. It's located at CR450E and was built in 1914 by the Lafayette Engineering Co.
This bridge may not be at this location anymore. There was all kinds of word that this bridge will be disassembled and moved to the Conner Prairie north of Indianapolis. The plan was reconstruct the bridge over the same river that far upstream, but it would probably be used for pedestrians and buggys. It would be fortunate for this to happen instead of the bridge being torn down.
Also back in 1998 I saw this other single span through truss bridge over the White River south of Gosport which is not listed in this website. I'm pretty sure it still exists. It looks like it was bypassed by a new bridge back in 1990 according to the new one's plaque. Someday, I'll have to check out to see if this one still exists.
