Yes, a box girder bridge. Part of my youth. A long way away too in Melbourne.
A PDF version is available here.
50 years ago, when I was a PhD student and still committed to a career in big bridges, Milford Haven and Westgate fell in just 4 months, with massive repercussions. When I was reminded of this by Colin Caprani via Twitter I was prompted to do something completely different this month.
In the end, because I am battling with a broken finger and a pile of un-started work, I opted to do this as a video so not many words here, just two pictures as tasters.
Milford Haven, now Cleddau in June 1970.
Westgate span 10-11 from the top of pier 10 in October.
I am sorry the audio quality is less than I hoped and there is a least one verbal error when I refer to New Zealand instead of Australia. It is also, at 44 minutes, longer than I planned and still only covers a small part of what there is to learn.
My hand is now a little less encumbered but still very reluctant to work for me!
Back to normal by the end of November, I hope.
