Looking down the side the Manchester Road bridge over the Peak Forest Canal. The roving bridge which is Grade II listed was built to allow horses pulling boats to change sides without being unhitched when the towpath moved from one side to the other. In the background is the railway bridge over Manchester Road.
For another view of this bridge and a fuller explanation of the term "roving bridge" see my post from December 2008.
