...Let’s say we have a boat sailing from the coast of a continent to another(the more the distance the better). Such boat has a tall pole(how tall is what I don’t know) with two motion/distance tracking “sensors” attached to it. One at the bottom and one at the very top. Due to the curvature if Earth,the distance registered by the top “sensor” will be bigger than the one registered at the bottom.
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 in (41.275 mm) farther apart at their tops than at their bases; they are not parallel to each other. The bridge's two towers are the tallest structures in New York City outside of Manhattan.
