What better way to start things off than with SW Seattle Street?
SW Seattle Street is a minor residential street in West Seattle that runs about ³/₁₀ of a mile from 42nd Avenue SW in the east to Sunset Avenue SW in the west.
It might seem strange that such a short street would be chosen to bear the city’s name — it was the only one to do so until 2010, when the first two blocks of Airport Way S were renamed Seattle Boulevard S — but this has more to do with unimaginative naming than with civic pride.
On August 4, 1869, Ike M. Hall — the executor of the estate of Norman B. Judkins — filed the Judkin’s (sic) Addition to the Town of Seattle, located just southwest of where the interchange between I-5 and I-90 is today. From north to south, the east–west streets are named Norman, B, Judkins, Addition, Town, and Seattle.
Portions of the original Seattle Street were vacated over the years (for example, in 1900, 1957, and 2000), and the construction of I-5 took care of the rest. However, when the city annexed West Seattle in 1907 it changed the name of Maple Street to W Seattle Street as part of rationalizing the street grid… and so the name lives on.
(The city itself, of course, was named after Si’ahl [siʔaɫ], better known in English as Chief Seattle of the Duwamish and Suquamish Tribes.)
So, why SW Seattle Street instead of Seattle Street SW?
In Seattle, east–west streets have the directional come first, and north–south avenues have it come last. The Wikipedia article “Street layout of Seattle,” which I helped write, has a more comprehensive description of Seattle’s addressing system, including the answer to this question:
Why was it W Seattle Street in 1907 but SW Seattle Street now?
In 1961, city ordinance 89910 “established a standard system of street name designations” so that in almost all cases streets within a given zone would carry the same directional. West Seattle avenues already carried the SW designation.
