You should be able to see what the previous wooden bridge looked like in the flood of March 2012, by clicking on the following link: 3 March, 2012. [Photo, on Bonzle, taken by Leonie.]
That bridge was still there a couple of weeks after the new concrete bridge opened, per the following photo on Bonzle: 22 November, 2012. [Photo, on Bonzle, taken by Leonie.]
While it looks like a substantial wooden bridge in that photo, the photo of the link above it, shows how precarious it was when Wollombi Brook was in flood. The current concrete bridge is at least 6 metres higher than the wooden bridge, so apart from having an approach blocked because low-lying flood water, it will be able to used for much longer.
The bridge looks like has been cast in place, using reinforced concrete 'I-Beams', supported by pairs of cylindrical concrete pylons. There is a decent sized pedestrian footpath on the southeastern side of the bridge.
Earlier to the wooden bridge (from 1932) there had been a flying fox over the Wollombi Brook to the Milbrodale side, for the dairy farmers on that side to ferry their milk cans (possibly 20 cans) to the Broke village side, and for school children to get to school, or home if otherwise cut off. The wooden bridge was built in 1965. [From a history sign on the Broke side.]
