Appearance and Structure of the Stonecutters Bridge:
Stonecutters Bridge is a cable-stayed bridge with two bridge towers, one located at Tsing Yi Island and the other located at Stonecutters Island. The Bridge has a total span of 1596m and a main span of 1018m. The Bridge spans the Rambler Channel and plays an integral role in the new Route 8 strategic link by connecting the busy Kwai Chung Container Port and the International Airport with the urban area of West Kowloon.

Deck
Steel was used on the deck of the main span. It is a twin-box girder arrangement. The box section deck provides convenient anchorages and has significant torsional properties.
Concrete was used on the deck of the back span.
