This stub of a street in Madison Park serves mostly as a driveway to the Canterbury Shores Condominiums, although it is public right-of-way. It appears to have been dedicated to the public in 1965, and its name was changed from 40th Avenue E the next year.
My assumption is the street was named for the condominiums, and that the condominiums were named for the Canterbury subdivision to the south, which was laid out in 1951. According to Shaping Seattle Architecture: A Historical Guide to the Architects, John L. Scott’s Canterbury Land Company purchased the land in 1938. (My further assumption is that the subdivision was named for Canterbury, England.)
Born and raised in Seattle, Benjamin Donguk Lukoff had his interest in local history kindled at the age of six, when his father bought him settler granddaughter Sophie Frye Bass’s Pig-Tail Days in Old Seattle at the gift shop of the Museum of History and Industry. He studied English, Russian, and linguistics at the University of Washington, and went on to earn his master’s in English linguistics from University College London. His book of rephotography, Seattle Then and Now, was published in 2010. An updated version came out in 2015.
