People have been known to jump (not dive!) from the middle of the bridge into the river – for fun rather than suicide. To give some idea of scale, the central arch is 16½ m (54' ) wide; guess the height for yourself. The water is fairly deep, illustrated by the fact that this reach of the river is used by scuba divers, but it still looks scary. It gets drastically deeper after heavy rain, and flood levels can cover the tops of the cutwaters (i.e. the base of the arches), but one wouldn't want to swim in such flows. A diver was swept away a few years ago, and emerged (unharmed) ~7 km downstream.
