It's a MOB trail bridge.
I see a bridge on street view if you're looking toward the lake.Is that a truss bridge?
I posted them for you Ashley.
Not sure how i would submit photos but i was so enamored by the sheer anger of this waterfall that i had to get closer. As i did, i found a way under the bridge and found a neat stone wall. No clue how old it is or its history. Id love to know but seeing as i was just passing through, i have no clue the history of this particular spot.
Thanks,Luke.I wasn't sure so I asked for confirmation.
