Two enormous arches of riveted wrought iron, each 455 feet long, leapt across the River Tamar between Devon and Cornwall, suspended 100 feet above the spring tide. The Admiralty had refused every easier scheme. Brunel had been forced into something nobody had ever built at this scale: a lenticular truss, a wrought-iron eye whose top arch pushes outward and bottom chain pulls inward in such perfect balance that the spans exert no horizontal thrust on their stone piers. Brunel himself, ill and exhausted, could not attend the opening. He died four months later. The Great Western Railway placed his name above the portals at both ends, where it has remained for 167 years.

The river is roughly 1,100 feet wide at Saltash; he sketched a double-track timber viaduct, central span of 255 feet, six approach spans, 80 feet of clearance above the water. The Admiralty, responsible for navigable waters, refused. He ra...

Royal Albert Bridge: The Lens

The top chord of each truss is a heavy tubular wrought-iron arch in compression; under load it tries to lengthen. The bottom chord is a pair of suspension chains in tension; und...

The Great Western's marketing department understood what they had. In its Cornish Riviera promotional copy, the writer SPB Mais descri...
