Hong Kong's eastern harbour crossing is on schedule for completion in early 1990. When completed, the tunnel will significantly ease cross-harbour road and rail congestion and will provide easy access to the eastern areas of Kowloon and Hong Kong island. The tunnel is one of the widest and longest immersed tube type in the world. Specific parts of the civil engineering works have been delegated by the main contractor to other contractors in the same consortium. It is made up of 15 units each 34.5 m wide, 9.8 m deep and around 120 m in length. The units are cast in three batches of five in a 5.5 hectare dry dock using three large batching plants working 24 hours a day. Once the ends have been sealed, they are towed out by barge, manoeuvred into position, ballasted and sunk into place; some 1.5 million cubic metres of material have been removed from the harbour bed to accommodate the sections. Once each unit has been sunk and connected, backfill material is placed on top to give the required safety factor.
