Whilst driving down the eastern side of Commonwealth Avenue Bridge, two men spotted a man climbing on to the parapet.
Fifty-four years ago, The Canberra Times reported on a fellow who was going to jump off the bridge into Lake Burley Griffin.
It was reported that the fellow was restrained by two men who drove past as he mounted the parapet. Mr JJ Watt, of Lyons, and Mr K Kennedy, of Deakin, told our reporter that they were nearing the centre of the bridge when they saw a man climb on to the parapet.
Mr Watt left the truck and approached the man while Mr Kennedy backed the vehicle so he could approach from the other side.
The 60-year-old fellow appeared to be a European migrant and he kept on repeating "this is the last country".
Both Mr Watt and Mr Kennedy had restrained the man and continued to talk to him pending police arrival. He was later taken to the police station.
The Department of the Interior warned the public that temperatures in Lake Burley Griffin drop to dangerously low levels during the winter.
