He designed the Lansdowne Bridge Rohri at Sukkur over the Indus River, which when it was completed in 1889 was the largest cantilever bridge in the world. The climax of his bridge-building career was considered to be the Howrah or Jubilee Bridge allowing trains to cross the Hooghly River near Calcutta; this was opened by the Viceroy on 21 February 1887.[1] He was appointed a Knight Commander of the Order of the Indian Empire (KCIE) in 1897.
