The
southwestern pylon is used by the New
South Wales traffic authority as a base
for their CCTV cameras overlooking the
bridge and the roads around that area.
The two pylons on the north shore are
now venting chimneys for fumes from the
tunnel under the harbour. The steel used
for the bridge was largely imported. About
79% came from Redcar in the North East
of England, the rest was Australian-made.
The granite used was quarried in Moruya,
New South Wales, and the concrete used
was also Australian made. The total weight
of the bridge is 52,800 tonnes, and six
million hand-driven rivets hold the bridge
together. Sydney Harbour Bridge as seen

you can see tourists climbing to the top.
Climbing the bridge has become a popular
tourist attaction. Sydney Harbour Bridge
in day.From the Sydney CBD side, motor
vehicle access to the bridge is normally
via Grosvenor Street, Clarence Street,
Kent Street, the Cahill Expressway, or
the Western Distributor.
Drivers
on the northern side will find themselves
on the Warringah Freeway, though it is
easy to turn off the freeway to drive
westwards into North Sydney or eastwards
to Neutral Bay and beyond upon arrival
on the northern side. Pedestrian access
from the northern side involves climbing
an easily-spotted flight of stairs at
Milsons Point. Pedestrian access on the
southern side is more complicated, but
signposts in the Rocks area now direct
pedestrians to the long and sheltered
flight of stairs that leads to the bridge's
southern end. These stairs are located
near Gloucester Street and Cumberland
Street in the Sydney Rocks area. The bridge
can also be accessed from the south by
getting on Cahill Walk, which runs along
the Cahill Expressway. Pedestrians can
access this walkway from Circular Quay
by a flight of stairs, or a lift, alternately
it can be accessed from The Botanical
Gardens.
