This street was created in 1895 as part of the Seattle Tide Lands plat (in full, Seattle Tide Lands as Surveyed and Platted by the Board of Appraisers of Tide and Shore Lands for King County, Washington). Streets were laid out from the northern tip of Magnolia (see W Semple Street) to West Seattle, but only the land southeast of Magnolia down to the Duwamish River was ultimately filled and developed.* (Magnolia’s tidelands were intended to become industrial land as part of the Bogue Plan, but this was rejected, and they have remained untouched west of the Elliott Bay Marina.)

* I certainly don’t want to minimize the extent of what was filled — over 92% of the tidelands, according to local historian and geologist David B. Williams.

As can be seen in the portion of the plat map reproduced below, the streets perpendicular to the shoreline in southwest Magnolia were named alphabetically after various cities in the United States. (Northwest of here, they were simply given letters of the alphabet, beginning with A and making it as far as O.) The namers began with Allegheny (Pennsylvania), and continued with Bangor (Maine), Chattanooga (Tennessee), Duluth (Minnesota), Erie (Pennsylvania), Fresno (California), Galveston (Texas), Hartford (Connecticut), Ithaca (New York), and our subject, Joliet (Illinois), before switching to yet another series.

Most of these streets have been renamed or vacated, but for some reason this never happened to Joliet Avenue, even when the Navy took over the Smith Cove piers and uplands in 1941 and 1942 to form Naval Supply Depot Seattle. Today, this is the Port of Seattle’s Terminal 90/91 complex, but as the quarter section map shows, it’s still crisscrossed by public right-of-way. It may very well take the proposed redevelopment of the uplands and Washington National Guard armory site to eliminate these paper streets for good.
