Workmen ride a 35,000-tonne section of tunnel across Victoria Harbour to its intended position in the Western Harbour Tunnel, one of several key projects associated with Hong Kong's new airport. In all, 12 such sections will be joined into an immersed tube containing six lanes for road traffic. The concrete sections were cast in a former quarry at Shek O, in Hong Kong's south-east, then towed to Junk Bay, in eastern Kowloon, for final checks before being tugged across the harbour where they were lowered into place, joined together and the ends were removed. Eight sections were lowered during 1995 and positioning of the last four was due to start in April, 1996. The two-kilometre tunnel will provide access to the west and south of Hong Kong Island, easing congestion at the two existing harbour crossings. A separate cross-harbour tunnel being built for rail traffic is also progressing well.
