I was not familiar with the bridge. Search engine says the towers of the bridge are 1⅝ inches (41.275 mm) farther between the tops than at the base. Can't tell by naked eye
I will look at the Bedord Experiment
I looked at a lot of images of it from different angles, there’s a definite curve to the bridge, and in their website they say that it was to be so long as to need to incorporate the curvature of the earth. So, when I saw the flat water under that bridge, it really gave me pause.
Then this bridge (with railroad!) is 102.4 miles long!! https://www.britannica.com/topic/Danyang-Kunshan-Grand-Bridge
