Like Queen Anne Avenue N, Queen Anne Boulevard is named for the neighborhood and hill, themselves named for the Queen Anne architectural style popular with builders in the 1880s. Unlike the avenue, though, the boulevard is not one single street, but a scenic loop incorporating many streets (and hence has no directional designation, such as Queen Anne Boulevard W).
The legislation establishing Queen Anne Boulevard was passed in 1907, and construction took place from 1911 to 1916. The Seattle Department of Transportation has had jurisdiction over the streets since 1942; jurisdiction over the landscaping remains with Seattle Parks and Recreation.
The loop is slightly over 3⅔ miles in length; the ordinance gives its route as follows (edited for style and current street names and directional designations, with notes added):
Extending from Prospect Street between Warren Avenue N and 2nd Avenue N, in a northeasterly direction*, to an intersection with Galer Street near Bigelow Avenue N; thence northerly following the general direction of Bigelow Avenue N as nearly as the contours of the ground will permit, to Wheeler Street; thence westerly to Nob Hill Avenue N; thence southerly to McGraw Street; thence westerly to 2nd Avenue N; thence northwesterly to Smith Street†, west of Warren Avenue N; thence westerly along Smith Street to a point east of 1st Avenue W; thence southerly to W McGraw Street and 2nd Avenue West‡; thence westerly to 3rd Avenue W; thence northwesterly to 5th Avenue W and W Smith Street§; thence northerly to W Raye Street; thence westerly to 8th Avenue W; thence northerly to W Armour Street; thence northwesterly to W Fulton Street; thence westerly to 9th Avenue W; thence southwesterly to 10th Avenue W and W Armour Street; thence southerly to W Wheeler Street; thence easterly to 8th Avenue W; thence southerly to W McGraw Street; thence easterly to 7th Avenue W; thence southerly to W Blaine Street; thence westerly to 8th Avenue W; thence southerly to W Lee Street; thence southeasterly to W Highland Drive and 7th Avenue West¶.
* Now the southern extension of Bigelow Avenue N.
† Now McGraw Place.
‡ Now the east half of W McGraw Place.
§ Now the west half of W McGraw Place.
¶ Now 8th Place W.
Notably, there is a gap in the loop; Highland Drive between 7th Avenue W and Warren Avenue N could have made it closed, but this was not done.
As noted in Bigelow Avenue N, neighbors’ yards often encroach on the public right-of-way, leading, among other things, to confrontations over chestnuts…
