SYDNEY'S GREAT BRIDGE.
WORK ON THE MAIN ARCH. LARGEST GIRDERS IN WORLD. [FROM OUR OWN CORRESPONDENT.] SYDNEY, June 28. that the work on the ten huge approach spans is almost complete, after tlirco and a-half years, the most interesting stage in the construction of the great Sydney Harbour bridge will shortly bo reached, that is, the actual spanning of the harbour without any pillar supports in the water. Iho end post of the mam arch span bridging tho water will shortly be placed in position by a 500-ton crane. Those and posts, four in all, and each 190 ft. in length, arc so immense that tlioy havo to bo fabricated and erected in sections. Placed end on end, and raised vertically, these great posts would be approximately tho same length as the world's tallest office building, the Woolworth in New York. They will be the largest bridge girders in the world. _ When the end posts havo been placed in position, tho gigantic work of bridging the water will proceed from both sides of tho harbour simultaneously, until the two half arches meet in the centre. With the aid of powerful hydraulic jacks and other gear, the two half arches will be brought together until the rivets have been inserted. Tho massive cables holding the two half arches will then be removed, and the bridge will be an actual fact.
