Summary
[edit]DescriptionIron Protector on Bridge No 130, Grand Union Canal - geograph.org.uk - 1462979.jpg |
English: Iron Protector on Bridge No 130, Grand Union Canal. When barges were towed by horses there were places where the tow rope could rub against the arch of a bridge. If they had come against the brickwork the hawser would act like a saw, cutting into the brickwork. For this reason iron bars were mounted on the vulnerable brick corners to avoid damage to the bridge.
