Throughout the course of the 20th century, the immediate streetscape neighboring Roslyn Place changed rapidly. Belgian block streets and trolley lines were paved with asphalt, the original Aiken Avenue wooden bridge was replaced with the current steel structure, Osterling and Rodd’s homes were demolished in the 1960s and replaced with condominium developments with private streets, and demise of the Pennsylvania Rail Road in the 1970s would lead to the creation of the Martin Luther King Busway to the North of the neighborhood. However Roslyn Place would remain a wooden block street in part because of the advocacy of its neighbors and the active stewardship of the City of Pittsburgh’s Department of Public Works.
