West End Mill

West End Mill as shown on an 1886 West Philadelphia property map.

Note: South Street appears on this map in a place that may surprise readers familiar with the famous street that connects the Schuylkill and Delaware rivers. South Street’s westward extension along the city grid devised by William Penn was interrupted by the Schuylkill, the University of Pennsylvania, and the Woodlands Cemetery. Around the turn of the 20th century, city planners revived Penn’s original name for South Street (Cedar Street) and applied it to the street’s extension from 45th (at the latter’s diagonal intersection with Baltimore Avenue) and 63rd streets. See “South Street (Philadelphia),” Wikipedia.org. A similar logic appears to explain the renaming of South Philadelphia’s Fitzwater Street as Walton Avenue in West Philadelphia.
