Design Features
Built between 1966 and 1968, it was the first cable-stayed bridge in Australia and among the first such bridges in the world. The main span is 206 metres (676 ft) long, suspended from a 91 metres (299 ft) high steel A-frame tower. The deck is 10.3 metres (34 ft) wide. The tower is constructed on the west bank of the Tamar river, on a solid dolerite rock base which carries 78% of the weight of the main span. The length of the bridge is 432 metres between abutments. The east bank is soft clay not capable of supporting a bridge. A causeway carries the highway across this softer base, supported by four piers built on piles driven up to 18 metres (59 ft) into the clay. The bridge deck is constructed of steel which is lighter than concrete, but required much more welding on site during construction.

Famous quotes containing the words design and/or features:
“Delay always breeds danger; and to protract a great design is often to ruin it.”
—Miguel De Cervantes (1547–1616)
“However much we may differ in the choice of the measures which should guide the administration of the government, there can be but little doubt in the minds of those who are really friendly to the republican features of our system that one of its most important securities consists in the separation of the legislative and executive powers at the same time that each is acknowledged to be supreme, in the will of the people constitutionally expressed.”
—Andrew Jackson (1767–1845)
