This street was created in 1895 as part of the plat of Seattle’s tide lands. As Seattle expanded to the south, it became obvious that Commercial Street (1st Avenue S) would not be the westernmost street east of Elliott Bay. Fortuntately, instead of using zero or negative numbers, they went with states: the first street west of 1st was named Utah, and the next, Colorado. (Some perpendicular streets were named Alaska, Vermont, Connecticut, Texas, Massachusetts, etc. There doesn’t appear to have been any particular order.)
Colorado Avenue S begins at S Royal Brougham Way and goes ⅓ of a mile to S Massachusetts Street. It begins again on the back side of the Starbucks Center and goes ⅘ of a mile to just south of S Spokane Street, and its final segment begins just north of Diagonal Avenue S and goes ⅔ of a mile to S Dawson Street.
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.
