Neighborhood: East Liberty
Frazee Way was originally called Warp Way, as shown in the 1924 Hopkins street atlas. Nearby Woof Way and Shuttle Way provide clues to the origin of these names: they are weaving terms. A shuttle, of course, is the wooden piece that holds yarn to be passed back and forth between the warp threads on a loom; the woof, or weft, is the resulting threads that run perpendicular to the warp. So Warp Way and Woof Way are quite appropriate names for intersecting alleys!
Warp Way was renamed Frazee Way by a city ordinance in 1919 (apparently the 1924 atlas hadn’t yet been updated).
