This street was created in 1925 as part of the plat of Ridgemont. Unnamed at the time, it was presumably later named after the subdivision. I say “presumably” because there is no record of its being named in Seattle’s online legislative database, which there should be if this was done after this part of town was annexed in 1953, and King County’s only goes back to 1969.

Ridgemont, as the below advertisement implies, was named for its location atop a ridge “commanding a magnificent view of Puget Sound and the Olympics.”

Ridgemont Way N begins at Greenwood Avenue N just south of N 125th Street and goes just over 425 feet southwest to N 122nd Street.
