Successfully obtained permission today and now we can all determine for ourselves. It looks a lot different on the North than from the South, which has high steep banks and foliage interfering.
I definitely agree this is more of a concrete culvert than an arch. I would guess this is a bottomless culvert and the bridge inspector coded the structure type as an arch, as oppose to a culvert during a past inspection. From what I understand this is common practice in some states, I know we try not to do this in Oregon, though we do have something similar in Ashland.
The NBI data is only as reliable as the inspection report it pulls the data from.
I've never really considered this an arch bridge, more of a older style concrete culvert. Driving over it you certainly cannot tell you are on a bridge since there is no sign indicating a crossing and no raise or bump in the road. Farmland, clump of trees, subdivision, farmland all at a speed of ~ 40 mph. Best view is from the North, whenever I get permission from the owner on that side.
