Keys to History
In the mid-19th century, the British engineer Robert Stephenson conceived of a bridge with a tubular framework. One of his first bridges was the Britannia, which spanned the Menai Straits in Wales. This bridge was equipped with two tubes through which trains passed.
This plan illustrates a section of one of the tubes on the Britannia bridge, still in the process of construction. Note that several workmen are busy inside the tube.
