Construction

Finally; this report shed the light on one of the most famous world bridge which is Sydny

Harbour Bridge, it was focusing on the main components and the way of construction. Its

unique design makes it easily recognizable and is seen by locals and foreigners alike as a symbol

of national pride. The bridge gave greater accessibility to all areas of central Sydney and

surrounding areas, which in turn saw a growth in population around these areas. It has, ever

since its opening, become an icon for Sydney and Australia, and due to its dramatic placement,

it has become the centre piece for many celebrations around the harbor. The bridge cost more

than other bridges in its construction because it needs different materials, professional labors

as well as professional engineers. The Sydney Harbour Bridge is the world’s largest steel arch

bridge and acts as a passage for rail, vehicular, bicycle and pedestrian traffic between the

Sydney central business district and the North Shore. The Sydney Harbour Bridge is also

significant as one of the world's greatest arch bridges. Although not the longest arch span in

the world, its mass and load capacity are greater than other major arch bridges, and no other

bridge in Australia compares with the Sydney Harbor Bridge in its technical significance. In

comparing Sydney Harbour Bridge with overseas arch bridges, Engineers Australia has drawn

attention to its complexity in combining length of span with width and load carrying capacity.

The construction of Sydney Harbour Bridge combined available technology with natural

advantages provided by the site. The designers took advantage of the sandstone base on which

Sydney was built, which enabled them to tie back the support cables during construction of the

arch, and to experiment with massive structures. Although designed more than 80 years ago,

the bridge has still not reached its loading capacity.
