150. The new typhoon shelter is formed by the construction of three overlapping breakwaters on the east and north, an 850 ft. long causeway from Kellett Island at the northwest corner to the waterfront road protecting the west with the existing breakwater of the old shelter on the south. For the construction of the breakwaters in an average depth of 16 ft. of water, a trench was excavated with a bucket dredger to remove the mud down to a sound bottom, the trench then being back-filled with sand on which was dumped the protective mounds of quarried granite ranging in size up to 5 ton blocks. 212,000 cu. yds. of mud were dredged for the foundation which were back-filled with 247,000 cu. yds. of sand. For the protective walls on the east and north, 244,000 cu. yds. of rubble were deposited by a 75 ft. cantilever crane up to a height of 17.00 C.D., the breakwaters being then faced with 22,000 cu. yds. of granite hand packed.
151. The causeway to Kellett Island was formed by end tipping from lorries after the soft mud had been removed by dredging. The causeway was faced on both sides with granite and has a 13 ft. wide roadway and 5'-6" footway which gives access to the Royal Hong Kong Yacht Club on the Island.
152. Central Reclamation. Although much smaller in area than the scheme at Causeway Bay, this reclamation of 9 acres of the foreshore of the centre of the Island business area, is attended by many more difficulties. Practically all the telephone and cable communications linking the Island with the Mainland and the outer world crossed the area and had to be picked up and moved before any work could commence. In addition twin 21" diam. steel submarine pipelines, feeding water to the Island from reservoirs on the mainland, cross the area and will have to be replaced on a new line before the outer seawall can be constructed over the existing line.
