Some highways in Montana are so flat and straight they appear to drop off in the distance. You will never get to that point where it drops off. Just keeps moving. Always figured it was curvature of the earth.

How about tall bridge supports that are so tall and far apart they are farther apart at the top than the bottom when they both are perfectly plumb.

The following quote is taken from this site:
https://www.reddit.com/r/engineering/comments/2mik11/structural_engineers_at_what_point_does_the/

"Because of the height of the towers (693 ft or 211 m) and their distance apart (4,260 ft or 1,298 m), the curvature of the Earth's surface had to be taken into account when designing the bridge—the towers are 1 5⁄8 inches (41.275 mm) farther apart at their tops than at their bases.[13]"

Round or flat, if I trip, I will fall down.....
