One from our Chinese conspirators
"The towers of the Akashi Bridge are made of steel, height above the
piers 283 m, 297 m measured from water level, at completion the
tallest bridge towers in the world. Due to the curvature of the
earth surface, the distance between the towers is 93 mm longer at
top than at base"
