Forth Bridge opened to rail traffic

Background. The Forth Bridge is a cantilever railway bridge located in the east of Scotland, approximately 9 miles west of central Edinburgh. It spans the Firth of Forth between South Queensferry and North Queensferry. Before the bridge's construction, ferries were the primary method for crossing the Firth, and railway trains could not pass directly between the North British Railway lines on either side without using rival company lines.

Engineering Significance. Designed by Sir John Fowler and Sir Benjamin Baker, the bridge was built on the principle of the cantilever, where a beam supports a central girder. Upon its opening, it held the record for the longest single cantilever bridge span in the world, a status it maintained until the completion of the Quebec Bridge in 1919. The structure is considered a symbol of Scotland and is a UNESCO World Heritage Site.

Opening Ceremony. The bridge was officially opened on 4 March 1890 by the Duke of Rothesay, the future King Edward VII. During the ceremony, he drove home the last rivet, which was gold-plated and inscribed. The bridge had been completed in December 1889 and underwent load testing in January 1890. Full express train services were delayed until June 1890 due to incomplete connecting lines.
