 By the following year, NY 342 was truncated westward to the hamlet of Conesville while a highway between NY 23 near South Gilboa and NY 30 southwest of Gilboa was designated as NY 297. The NY 297 designation was short-lived as it was removed c. 1936. NY 342 was extended westward over the former routing of NY 297 in the mid-1940s; however, the designation was eliminated in the late 1940s. While the portion west of NY 30 became CR 14, the section east of NY 30 was retained as a state highway. When the modern reference route system was created, the Gilboa – Conesville state highway was designated as NY 990V.
