This street first appears in the 1875 plat of the Northern Addition to Seattle, W.T., filed by James Marston McNaught (1842–1919) and his wife, Agnes Martha Hyde McNaught (1856–1918). James was “a wealthy lawyer working in the railroad industry.” I assume it was named for Martin Van Buren, eighth president of the United States, and not for his namesake, Martin Van Buren Stacy, a Seattle real estate developer, though I wouldn’t be surprised if McNaught and Stacy knew each other, as their dwellings, in addition to that of Henry Yesler, were considered “the three most lavish mansions in the city.”
I wasn’t sure whether to label Van Buren Avenue a “paper street” or not. Unlike W Semple Street and Albert Place W, part of the right-of-way has actually been improved (see below). However, like those two streets, it is not signed; and unlike Semple, there are no buildings with Van Buren Avenue addresses. (There are two houses on the street, but one has a W Prospect Street address; the other, an Elliott Avenue W address.)
The right-of-way stretches from just southeast of W Prospect Street, northeast of Elliott Avenue W, to where the Magnolia Bridge onramp turns west at W Garfield Street. The first 350 or so feet are drivable. There is also a foot trail through the Southwest Queen Anne Greenbelt in the right-of-way, beginning at the east end of W Lee Street and heading southeast. Lastly, just under 600 feet of the Magnolia Bridge onramp is located in the right-of-way. It could conceivably be signed Van Buren Avenue W instead of W Galer Street Flyover, but this is not the case.
