NY 204 was truncated to East Chatham following the extension of NY 295. It remained in this truncated form until it was eliminated entirely in the early 1940s. A small segment of NY 204's original routing between the then-proposed routing of NY 22 and the state line at West Stockbridge, Massachusetts, became NY 432 after NY 204 was realigned . As originally planned, NY 22 would have followed a more westerly alignment through Austerlitz and Canaan; however, the road was ultimately built on a path that supplanted most of NY 432. As such, the NY 432 designation was removed after the new stretch of NY 22 opened in 1940. A small section of NY 432's former right-of-way between NY 22 and the Massachusetts state line is still state-maintained as NY 980D, an unsigned reference route.
