It is interesting to see when some home videos are taken, what appears incidental at the time can become very interesting 40 years later. My dad is fishing to the side of a wide expanse of water in one cine film, next to a large bridge made up of a box section girder arrangement. The film then proceeds to pan across this bridge a few times. It is a famous one which all bridge engineers should know and people knowledgable in the work of George and Robert Stephenson as well. It is the original box girder Britannia Bridge over the Menai Straits, prior to the fire in 1970 which effectively destroyed the historic bridge.
