The foundation stone for the first Tay Bridge was laid in Dundee on 22 July 1871, following the 1870 Act that authorized its construction. Designed by Thomas Bouch for the North British Railway, the bridge faced significant engineering challenges, including deep bedrock issues and design changes. Completed in 1878, it was the longest bridge in the world at the time, though its subsequent collapse in 1879 led to Bouch's reputational decline.

Background and detail

Background. Proposals for a bridge over the Tay emerged in 1854 to replace the train ferry service. The North British Railway (Tay Bridge and Railways) Act received royal assent in July 1870, enabling construction. Thomas Bouch, a prominent railway engineer, designed the structure for the North British Railway, which had previously employed him as manager and engineer.

Construction. The foundation stone was laid on 22 July 1871. Construction faced difficulties as the bedrock proved too deep for pier foundations by December 1873. A new contract was issued in 1874, and design changes increased costs and delays, exacerbated by the fall of high girders in 1877. The first engine crossed in September 1877, and the bridge was completed in early 1878.

Completion. The bridge was opened for passenger traffic in June 1878, having been the longest in the world upon completion. Thomas Bouch was made a burgess of Dundee for his services. Queen Victoria crossed the bridge in June 1879, and Bouch was knighted shortly after, recognizing his achievement before the disaster.
