This link provides the most common with the famous foot trail from GA to ME as pretty much all have it except for rare instances like the Trail Crossing on US 9W and US 202 at Bear Mountain, NY that uses an underpass made especially for the Trail.

How many non freeway roads have a grade separation between asphalt and dirt other than the one I just posted?

Here in Fairfax County, Jeff Todd Way uses an overpass to cross over a dirt road on Fort Belvoir property. Is that the sort of thing you mean?

Similar to that, HI 200 has a bridge over an unpaved road (maybe a tank trail) in the Army's Pohakuloa Training Area on the Big Island:

Is this specific to the Appalachian Trail, or just any unpaved trails that go under any non-freeway?


There will be tons of cases where a trail adjacent to a river or stream goes under the road along with the river or stream.
You've also got the Erie Canal - while much of that trail is paved in the Rochester area, I'm sure there are segments elsewhere that aren't. As for examples that aren't related to a water crossing and have a custom-built over/underpass just for the trail, I think those are going to be pretty rare.

Grade separations between non-freeway roads, streets, etc and pedestrian/bicycle pathways are common as dirt.

The Laurel Highlands Trail has its own bridge over the Pennsylvania Turnpike:

Two cart paths at the Oakmont Country Club near Pittsburgh, PA have separate bridges over the Pennsylvania Turnpike, too.

The most known one in Massachusetts at least.

I'm not sure, but I have walked across I-70 on the Appalachian Trail and also driven under it on I-70.
