SYDNEY BRIDGE

A COLOSSAL WORK

A most interesting address on thai colossal undertaking of building th« bridge across Sydney Harbour was given at the Wellington Botary Clubi luncheon to-day by Mr. Lawrence Innejr the engineer in charge of the work. Th# drawing of the plans, the quantities of granite and steel, the making of the huge cables, and the details of :th«| carrying out of the huge undertaking were all described.,

I There were, said Mr. Innes, no les* than 51,000 tons of steel in the bridge* One of the critical operations was th* sinking of the tunnel, which was of unusual depth, and the most difficult part was the formation of ja perfect curve, going down at 45 degrees and' around a radius 140 ft. The most anxious time was the joining of the halves of the great arch, for. a strong, wind was blowing at the time, and the* steel was, of course, affected by the heat. The speaker said he would never forget the moment when the successful completion of this critical operation occurred; when the flags were flown as a signal of success, and the crowds, in the steamers on harbour below sang the National Anthem. Mr. Innes was listened to throughout his address with the closest attention, and he was applauded and given a hearty vote of thanks.
