Forth rail bridge - Baker and Fowler
Speaking of great nineteenth-century bridges, here's Scotland's magnificent Forth rail Bridge, a spectacular cantilevered steel bridge completed in 1890.
The photo at right gives an idea of the epic scale of this structure that links Edinburgh to the highlands, and stands exposed to the worst the North Sea can throw at it.
A famous demonstration of the structural principles at work in this innovative bridge was undertaken by the proud designers. Click on the pic to above for a more detailed description.
