THE GREAT ZAMBESI BRIDGE. PERSPECTIVE VIEW OF THE VICTORIA FALLS AND GORGE. that at the centre the bridge is 15 feet deep. The vertical girders have an upward taper, or “ batter,” of 1 foot in 8 ; and the booms of the arc approach one another towards the centre of the bridge, so that the distance between them diminishes from 53 feet 9 inches at the main bearings to 27| feet at the crown. This gives sufficient room for a roadway, 30 feet broad between the parapets, designed to carry two tracks of rails.
