Thoroughfare (pop. 1961, 2) is a resettled fishing community located at the northeast corner of Random Island, facing the passage between Random Island and Ireland's Eye. There were 18 people in Thoroughfare in 1845, with the population increasing to 40 by 1869.

The peak population recorded at Thoroughfare was 74, in 1921. Most people were inshore fishermen who also engaged in winter logging for small sawmills in Random Sound. There were also mercantile premises at Thoroughfare, supplying fishermen on eastern Random Island and at Ivanhoe, on Ireland's Eye. The population of Thoroughfare declined after 1930, to 50 people in 1945. When a few families left in the early 1950s the community was scarcely viable. The remainder left in 1958 and 1959, except for Moses and Theodosia Brown, whose advancing age forced them to move in 1961.
