March 1890: Pictures showing various aspects of building the Forth Bridge: its size compared with the Eiffel Tower; a demonstration of the cantilever process; a cassion being towed into position and a general view of the Inchgarvie cantilever. The Forth Bridge spans the Firth of Forth at Queensferry in Lothian and is over a mile long. The steel cantilever construction was designed by John Fowler and Benjamin Baker to carry a double-track railway line and a road over the river. When it was completed in 1890 it was the longest bridge of its kind and considered a great achievement in engineering. Graphic - pub. 1890 (Photo by Hulton Archive/Getty Images)
