A quick break in the action - promoted from the diaries ~ whataboutbob
We have seen so many bridges being destroyed by water the last couple of days, that I want to show you a bridge that needs water to open.
It is the hydraulic Swingbridge in Newcastle Upon Tyne
Earlier Bridge Blogging:
Muengstener Bruecke (Aug 25th)
Mostar Bridge (Aug 18th)
They started building it in 1873 and finished three years later. What has always impressed me, is its smoothness and elegance. When it opens its motive power is supplied by a set of hydraulic engines that are worked by electrically driven pumps. Every time it turns its 900t need to be moved.

Armstrong was one of the first to use Waterpower to produce electricity and he also installed it in his private house.
