NY 31 was truncated to NY 365 in Verona in the early 1940s; as a result, NY 31 and NY 234 now had a common terminus. Despite this fact, the two routes continued to co-exist for the next 40 years. On April 1, 1981, ownership and maintenance of the Churton Road portion of NY 234 was transferred from the state of New York to Oneida County as part of a highway maintenance swap between the two levels of government. Two of highways that the state received in return were Stuhlman Road (CR 81) and the segment of Youngs Road (CR 13) between Stuhlman Road and Churton Road (NY 234). The two new state highways did not become a rerouting of NY 234, however, as the NY 234 designation was eliminated at this time. Instead, NY 31 was extended southeastward over NY 234's former routing to Vernon, from where it continued to Vernon Center by way of NY 5, Stuhlman and Youngs Roads. Churton Road was redesignated as CR 94.
