Note that the map is oriented with north to the left. Parkview Avenue is the roadway shown running up and down the right side of the map. The road crossing Parkview near the bottom of the map is identified as Twelfth Street. In 1963 the U.S. 131 freeway was finished between West Main Street in Kalamazoo Township and Schoolcraft (Shaver Road intersection), bisecting Twelfth Street and Parkview Avenue. The north half of Twelfth Street was terminated at Parkview and renamed Drake Road, the two halves of Parkview were reconnected with a freeway overpass, and an extension to the south half of Twelfth Street reconnected it with Parkview, just west of the overpass.

The State of Michigan acquired the Asylum Farm property in 1887. From 1887 to 1969 the Farm was part of the State's mental health system. In 1969 all remaining patients and staff moved to the State Psychiatric Hospital on Oakland Drive in Kalamazoo, and the property was deeded over to Western Michigan University in 1975. Shortly afterwards the tunnels and underground structures not sealed or demolished in 1965 were dynamited, as further deterioration was making them unsafe.
