Structure
Tsing Yi Bridge is formed by 5 levers, identical pairs of arms supported by stands, 18 metres (60 feet) above the water, in the middle, with round-shaped caissons on the seabed.
The arms are made of pre-tensioned concrete. Their cross section is of hollow boxes. There are some power cables and two oil pipes inside the boxes. Both sides of hollow boxes have water pipes for the Tsing Yi Island.
On the bridge, 7 metres (24 feet) width is provided for vehicles with a 1.5 metre (5 foot) wide pedestrian walkway on each side.
The bridge is designed to withstand typhoons, strong waves and accidental collisions by ships.

Famous quotes containing the word structure:
“What is the most rigorous law of our being? Growth. No smallest atom of our moral, mental, or physical structure can stand still a year. It grows—it must grow; nothing can prevent it.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“If rightly made, a boat would be a sort of amphibious animal, a creature of two elements, related by one half its structure to some swift and shapely fish, and by the other to some strong-winged and graceful bird.”
—Henry David Thoreau (1817–1862)
“The structure was designed by an old sea captain who believed that the world would end in a flood. He built a home in the traditional shape of the Ark, inverted, with the roof forming the hull of the proposed vessel. The builder expected that the deluge would cause the house to topple and then reverse itself, floating away on its roof until it should land on some new Ararat.”
—For the State of New Jersey, U.S. public relief program (1935-1943)
