Batman Bridge, off Tamar Hwy, Tasmania
The 'Batman Bridge' is a modern bridge crossing the
Tamar River in northern
Tasmania. It was built from
1966 to
1968. It was the first
Cable-stayed bridge in
Australia. The main span is 206 metres (675.8 ft) long, suspended from a 91 metre (298.5 ft) high sloped A-frame tower. The deck is 10.3 metres (33.8 ft) wide. The bridge is on the
Batman Highway connecting the
West Tamar Highway to the
East Tamar Highway.
The tower is constructed on the west bank of the Tamar river, on a solid
dolerite rock base. 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.
The bridge overlooks the
Deviot Sailing Club. It is named after
John Batman,
Launceston businessman and founder of
Melbourne.
