A Tale of 2 Bridges.

 Here is an old abandoned and unusable timber bridge somewhere in the bush between Nagambie and Violet Town. I would love to know more about it and it's history.
    In contrast is the much used wrought iron, bluestone and timber Redesdale Mia Mia Bridge.



 
The Redesdale Bridge is a wrought iron and timber structure with bluestone abutments which was installed over the Campaspe River in January 1868, although the bridge actually bears the date 1867. In 1859, the "Herald of the Morning", a ship carrying a cargo including 350 tons of ironwork for the Hawthorn bridge, caught fire and was scuttled a quarter of a mile off the jetty at Sandridge. A Melbourne salvaging firm raised the ironwork from the bottom of the bay, but after details of an arranged sale to the government caused a scandal in Parliament, the material was sold privately to the Melbourne foundry Langlands & Co. Two hundred tons of it was sold to the goldfields shires of McIvor and Metcalfe for only £1000. The bridge was designed by engineer TB Muntz and built by a contractor named Doran, and was completed late and considerably over budget at £6274. The bridge spans 45.7m across the river and has two roadways which are carried between three metal lattice girders in a through truss configuration. The design for the Hawthorn bridge had the deck supported over the trusses, and to stiffen the through truss configuration three sets of distinctive paired arches connect the trusses above the roadways. The roadway decking is constructed of longitudinally placed timbers on timber cross girders which rest on the lower chords of the trusses.

The second bridge looks like you should be able to pick it up by the handles and carry it away.
I have been reading a book about designing art quilts and your pictures would do very well for the design exercises. I must go through some of my pictures and see if I have any such inspirational images.
The book is by Elizabeth Barton and is called Inspired to Design. So far I've only been inspired to read the book.
