The calculation in the image is based on the 8 in per mile squared rule of thumb, which calculate the amount of drop of a tangent line to a sphere with the radius of 3,959 miles. But the photograph is taken high up so you are not showing the tangent line of the bridge. In stead you need to take the photograph at one of the ends of the bridge like Soundly has done at Lake Pontchartrain.

they didn't make the bridge with calculating the curve--->that's the point!
Then why is the "8 in per mile squared rule of thumb" in the picture? Also on a globe Earth while building a bridge there would be no need for taking the curvature into account. But back to the video I posted a link to, how is that possible on a flat Earth?
don't you understand me at all??the point is that the bridge is build without taking the curvature into account!!understand?!
No I don’t understand. The bridge is obviously not built in one 25 mile long piece but in small segments. So there is no need on a globe Earth to take the curvature into account while building a long bridge. Why do you think there would be?
:'-) i'm speechless,..this is not good for my brain..end of debate
If you claim making a 25 mile long bridge on a globe Earth should somehow take the curvature into account, you also should be able to explain how and why in more detail. And since a bridge is obviously built in small segments there isn’t any need to consider curvature.
