Cables

The key to a cable stay bridge is definitely the strength of its cables. The Cooper River Bridge's 1546 foot main span is suspended by 128 individual cables between the support piers. Cables are anchored on the deck level and inside of the diamond towers. Each cable can hold over one million pounds or 500 tons.

A single cable is composed of strands. A strand is composed of seven wires, six wires twisted around one center wire. Some of the strongest cables on this bridge are formed by 90 seven-wire strands. To protect the cables from changing weather conditions they are in a poly-ethylene (HDPE) pipe. The white pipes used on our bridge range in diameter from 12 to 20 inches.
