1966 Map of Marion

About this map

The Scioto River and Olentangy River corridors anchor this mid-century survey of Central Ohio, revealing a landscape defined by its river-valley settlements and burgeoning post-war infrastructure. Large urban centers like Columbus, Marion, and Mansfield are shown at a pivotal moment of expansion, connected by the growing interstate system of I-71 and I-70. The map documents significant institutional footprints, including the State Reformatory near Shelby and the campus of Ohio State University.
