Like its twin, Westmont Way W, this street was created in 1915 as part of the plat of Carleton Park, which “afford[ed] a scenic frontage for every building lot in the addition,” according to The Seattle Times. Just as Westmont faces the Olympic Mountains to the west and southwest, Eastmont faces the Cascades to the southeast.

Beginning at Eastmont Place, a pocket park at the south end of Westmont Way W, it goes around 850 feet northeast to W McGraw Street, where it becomes 36th Avenue W.
