This 275-foot-long diagonal street connects 23rd Avenue E to 24th Avenue E between E Ward Street and E Helen Street, allowing the arterial that begins at Jefferson Park on Beacon Hill to have “an easy grade to the Boulevard and Washington Park,” as the advertisement below for the Capitol Hill Addition, Division No. 6 in the October 28, 1905, issue of The Seattle Times explains. (The prediction that “in the near future there is almost sure to be a street car direct to the University” along this route was an accurate one.”
The plat was filed at the request of H.S. Turner on May 25, 1905. Herbert S. Turner (1866–1941) was also involved in developing parts of Montlake, the International District, and the University District.
This was a route I took often as a child, and my working theory then was that it was called Turner because, well, you turned onto it when going from 23rd to 24th, or vice versa. Now, 40 years later, I know better.
