“ I hope there are no Australians in the audience,” said Mr A. Tyndall when he recalled that he had seen over an arm of New York harbour a bridge with a longer span than the structure over Sydney Harbour, which bad been commenced after the latter had finished before it (states the Christchurch Press). But the largest bridge in the world was being constructed over the Hudson River. Its span was 3500 feet in length, twice that of the Sydney bridge. The deck was suspended by four ropes, each three feet in diameter, containing 107,000 miles of wire. The towers were 635 feet high and the anchor block at one end contained more concrete than the whole of the Arapuni electric works. The cost of this block was £500.000, and of the complete bridge £12,000,000. It was the boldest engineering feat yet attempted in the world.
