About this map

Baltimore Friendship International Airport anchors this mid-century look at the expanding suburbs south of Baltimore. The landscape is defined by the heavy infrastructure of the Baltimore-Washington Parkway and the Harbor Tunnel Thruway, which cut through established communities like Linthicum Heights, Lansdowne, and Elkridge. This edition captures the corridor during a period of significant growth, noting urban expansion in purple while preserving the footprint of local institutions like St Johns Ch and the United Hebrew Cemetery. Along the Patapsco River, the boundaries of Patapsco State Park offer a contrast to the industrial and transit-focused development elsewhere. Local genealogy is supported by the detailed marking of scattered schools and churches, including Wesley Grove Ch and Harmans Sch, alongside smaller hamlets like Ehrmansville and Shipley Corner that were increasingly integrated into the metropolitan sprawl.
