The Forth Bridge is among the world’s most well-known bridges. It's regularly pictured on postcards and in books on Scotland and is heralded as one of the country's most distinctive engineering accomplishments. The structure is comprised of a trio of bridges across the Fourth alongside the Forth Road Bridge and the recently constructed Queensferry Crossing.

The bridge links North and South Queensferry. It spans well over 8,000 feet and has been operational since 1890. It was the first major structure in the United Kingdom composed of steel. The Forth Bridge was also the longest single cantilever bridge in the world upon opening, currently, it's the second-longest.

As one of many designated UNESCO World Heritage Sites across Scotland, the bridge continues to amaze visitors as a remarkable engineering structure from the Victorian era. Despite massive advancements in technology since it opened, the bridge remains mostly unchanged and still manages to facilitate 190-200 trains daily.
