between Middleport and Medina. NY 31 was realigned on January 1, 1949, to follow its current alignment between the two villages. The former routing of NY 31 was redesignated as NY 31E, a northerly alternate route of NY 31. The alignment of NY 31E has not changed since that time; however, ownership of parts of the route has changed hands over the years. Until 1998, NY 31E was state-maintained from its western terminus in Middleport to the Medina village line. On October 1, 1998, ownership and maintenance of NY 31E between NY 271 in Middleport and the Niagara–Orleans county line was transferred from the state to Niagara County as part of a highway maintenance swap between the two levels of government. This section of the route was subsequently co-designated, but not signed, as CR 143 by Niagara County.
