Laid out in a traditional New England plan, Solon, like many of the neighboring townships, established a public square in its town center. In conjunction with townships to the north, a north–south corridor was established through the town centers of Solon, Orange, and Mayfield townships (from south to north, respectively) and, accordingly, was named SOM Center Road (now Ohio 91). Solon Township included the current municipalities of the City of Solon and the villages of Bentleyville and Glenwillow. In 1927, Solon was incorporated as a village and later became a city in 1961, operated under the mayor-council form of government.
