On a similar note as the post above, I-64 over US19 in Beckley, WV springs to mind, of the high overpasses I have seen from my own POV:

(Without going back thru the rest of the thread to see if this was mentioned) Bridges that go over rivers and need some extended height for marine traffic, tend to be high overpasses for roads near to or alongside the river, such as https://goo.gl/maps/jAzSYh6WPWr .

Here's this bizarre bridge on Marion Co Route 316 in Florida.


https://www.google.com/maps/@29.372035,-81.8987776,3a,60y,127.36h,90t/data=!3m6!1e1!3m4!1spUr3Pe7AvLwV2PlORViJuQ!2e0!7i13312!8i6656



It starts on the ground and goes to rise above the treetops, then suddenly goes back down, only to clear... this??



https://www.google.com/maps/@29.3722574,-81.8990698,3a,75y,130.71h,94.44t/data=!3m6!1e1!3m4!1sYoia_y1-mUD-6kFvlU7Xfg!2e0!7i3328!8i1664


I have no idea why that is. Part of the height could be due to the higher elevation on one side, but that still doesn't explain why it continues to go higher to clear a random road in the middle of the woods in extremely flat terrain. The wood around the supports would be to prevent boats from hitting the supports, which may  mean a waterway may have either existed or been planned for this location that would need to clear tall water traffic, this is the only plausible explanation I can think of. There's also a dam further upstream.


 Possibly, perhaps an industrial installation was planned which would have needed to have a canal with large cargo, or something like that? Like the bridge before the John Stennis Space Center in Mississippi. I don't know.


The presence of some sort of waterway or installation is also supported by not only a dam, but also what appears to be this abandoned lock and dam next to it:


https://www.google.com/maps/@29.3784733,-81.9034023,684a,35y,95.4h,23.29t/data=!3m1!1e3


The orientation of this meant it would have likely went under the bridge.


And also what appears to be this gated bridge and another waterway:


https://www.google.com/maps/@29.3774103,-81.8970085,244a,35y,95.4h,23.39t/data=!3m1!1e3


Through the process of looking at the area and writing this post at the same time, I think I can safely conclude that a waterway was planned here and never done or abandoned or something like that, hence the ridiculously tall bridge.

The above bridge adjacent the Eureka Dam is mentioned in Wikipedia's article on the Cross Florida Barge Canal.

Huh, that's really neat. I never knew that was a thing.
