Great added photos! In the first photo, this bridge appears to have one distinctive feature: a (somewhat lazy) guard dog.

The first seven spans (in the picture) were replaced with a levee, they were moved to different locations through out the country. The remainder of the bridge is original not having been replaced. The original bridge is still being used today.
