and 1934, is his most well-known work. From the outset, it was designed on a large scale; it is still the longest, widest road tunnel in Great Britain. Basil Mott was Engineer for the works, in association with J. A. Brodie, Engineer for the City of Liverpool. His partnership (by then named Mott, Hay and Anderson) designed and supervised the construction of the Mersey Tunnel in its entirety. In 1924, he was elected President of the Institution of Civil Engineers. In 1926 he was hired by Southampton council to investigate the various options for building a fixed crossing across the lower River Itchen. Along with proving costs for a tunnel and a high level crossing he recommended a low level opening span bridge. Basil Mott's other post-WW1 works include the extension to Morden of the Northern line, the enlargement of the original C&SLR tunnels from 10' 6" to 11' 8" (using a tunnelling shield which could be worked at night but through which trains could drive during the day), the Jubilee Bridge and work on the Tees Newport Bridge. In 1930, aged 71, he gave evidence to a British government inquiry on the engineering aspects of a proposed Channel Tunnel (which was not built, though Mott, Hay and Anderson designed the bulk of the successful scheme for Channel Tunnel half a century later). In the same year he was created a baronet. In May 1932 he became a Fellow of the Royal Society—a rare honour for a civil engineer. He died on 7 September 1938, in London. The baronetcy is currently held by his great-grandson, David Hugh Mott (born 1952).
