Flooding washed away Oldham Road in Denshaw during the weekend of May 30th/31st 1964 and to keep traffic moving the gap was bridged by a Bailey Bridge, a portable structure developed for military use. This was my first encounter with one but not my last as two appeared in Greenfield whilst the canal and river bridges there were renewed (see the 10 and 180 collections). 428 is still in original lined-out livery at this time. It's difficult to imagine now the traffic being controlled by these two-aspect traffic lights, but temporary ones were always like that then.
