The Forth Railway Bridge Then and NowThe Forth Railway Bridge Then and Now
The Forth Railway Bridge under construction, seen from South Queensferry, Scotland, taken by an unknown photographer in 1887. Constructed over seven years by engineers Sir John Fowler (1817-1898) and Sir Benjamin Baker (1840-1907) and completed in 1890, it was the largest steel bridge of its time.

Thanks to a recent coat of extremely weather-resistant paint, the bridge is now free of painters and scaffolding for the first time since it was built.
