There is a second bridge just to the north of here of similar design

Actually, the Waterford Bridge, a large single-span truss bridge in Dakota County and featured on this website, also has the jack-arch deck.

Yes, Nathan. And what is even more unique is the fact that this jack arch deck design is lined up horizontally instead of vertically. Basically the deck is encarved vertically in a rectangular fashion, while the jacked arch design is done horizontally in each of the rectangular encarvings. This and the smaller spans are the only ones in the state that have this design and therefore are eligible for the NRHP.

This bridge appears to have a jack arch deck, or something similar to a jack arch deck. Never seen one on a concrete girder bridge before.
