Infrastructure is a key element to Hong Kong's continuing development, and a source of huge economic and employment gains. Stonecutters Bridge , which straddles the Rambler Channel at the entrance to the busy Kwai Chung Container Port, opened to traffic in December. With a main span of 1 018 metres, the bridge has the second longest cable-stayed span in the world, and forms an essential part of Route 8 – a new highway linking the border crossings of the northern New Territories with Lantau Island.
