I drove past this bridge on Saturday, it is beautiful and unique! So glad it is preserved in place! Sorry, I did not get any new photos, I was in the middle of a blizzard! I hope to go past this one again in the spring and will get some new ones....

For those not understanding the comment Mike made, in Michigan bridge plaques often list and title the bridge based on on the funding source at the top of the plaque thus at the top of this bridge the plaque reads Federal Aid Bridge

Heh, Hyde's 1976 inventory refers to this as "Federal Aid Bridge" (with quotation marks).
