History

Lua error in package.lua at line 80: module 'strict' not found.

Prior to the completion of Ronald Reagan Cross County Highway in 1997, the central portion of State Route 126 between Ross and Montgomery consisted of West Kemper Road, Springfield Pike (State Route 4), Glendale Milford Road, Kenwood Road, and Cooper Road.^[3] On October 28, 1997, the Ohio Department of Transportation (ODOT) took over Ronald Reagan Highway, except for the segment west of Colerain Avenue.^[4] State Route 126 was rerouted over the highway, while Kemper, Glendale Milford, Kenwood, and Cooper roads were returned to local authorities.^[5]
