The Forth Bridge is a cantilever railway bridge over the Firth of Forth in the east of Scotland, 9 miles (14 kilometres) west of Edinburgh City Centre. It was opened on 4 March 1890 and spans a total length of 8,296 feet (2,528.7 m). It is sometimes referred to as the Forth Rail Bridge to distinguish it from the Forth Road Bridge, though this has never been its official name.
