In a footnote to the article he states "I have with the above constructed fourteen bridges upon this plan, all of which practically prove the correctness of my invention." Another Dredge suspension bridge in India was erected over the entrance to the wet docks at Kidderpoor near Calcutta in c1845. This had a 120 ft central span and a 24 ft wide platform. In the mid-nineteenth century, Dredge lived at 22 Sion Hill Place, Bath, also known as Gothic Cottage 27, which is now a Grade II listed building. Married to Anne Vine, there were at least three children, including a daughter, Elizabeth, and two sons. The elder son, William, was an engineer, as was a younger son, James Dredge Jr. (1840–1906), who was also a notable journalist of "Engineering", until paralysis forced him to end his participation in the journal.
