NY 239 began at an intersection with NY 354 just west of the Erie–Wyoming county line in the town of Marilla. The route then traveled to the northeast, climbing in elevation as it proceeded onward. It then made a turn to the north, descending in elevation. Running at about a height of {{convert|900|ft|m}} above sea level, NY 239 crossed into the town of Alden and continued toward downtown.{{cite map |url=http://gis.ny.gov/gisdata/quads/drg24/usgspreview/index.cfm?code=o42078g4 |title=Cowlesville Quadrangle – New York |publisher=United States Geological Survey |year=1949 |scale=1:24,000 |series=7.5 Minute Series (Topographic) |access-date=May 22, 2009 |archive-date=March 4, 2016 |archive-url=https://web.archive.org/web/20160304051059/http://gis.ny.gov/gisdata/quads/drg24/usgspreview/index.cfm?code=o42078g4 |url-status=dead }} NY 239 continued northward, passing nearby Henskee Road, a connector between NY 239 and County Line Road, which ran parallel to NY 239 along the Erie–Genesee county line. The route dipped further in elevation, entering the village of Alden. Inside the village, it passed the Buffalo Water Filtration Plant to the west and crossed the Conrail-owned Southern Tier Line. NY 239 passed through a primarily residential area of the village just before terminating at US 20 in the village center.{{cite map |url=http://gis.ny.gov/gisdata/quads/drg24/usgspreview/index.cfm?code=k42078h3 |title=Corfu – New York |publisher=United States Geological Survey |year=1984 |scale=1:25,000 |series=7.5 x 15 Minute Series (Topographic) |access-date=May 22, 2009 |archive-date=March 4, 2016 |archive-url=https://web.archive.org/web/20160304064358/http://gis.ny.gov/gisdata/quads/drg24/usgspreview/index.cfm?code=k42078h3 |url-status=dead }}

NY 239 as part of the 1930 renumbering of state highways in New York to an alignment extending from NY 35 in the village of Alden to NY 98 in the village of Attica by way of the hamlet of Cowlesville. The east–west road linking NY 239 near Cowlesville to Two Rod Road (then NY 358) north of Marilla was initially unnumbered.{{cite map |title=Road Map of New York |year=1930 |publisher=Standard Oil Company of New York |cartography=General Drafting}} It became part of a realigned NY 354 {{circa|1935}}.{{cite map |title=Road Map of New York |publisher=Texas Oil Company |year=1934 |cartography=Rand McNally and Company}}{{cite map |title=Road Map & Historical Guide – New York |publisher=Sun Oil Company |year=1935 |cartography=Rand McNally and Company}} NY 354 was extended eastward on January 1, 1949, over NY 239's alignment to a new terminus in Attica. As a result, NY 239 was truncated to its junction with NY 354 in the town of Marilla.{{cite news |title=Highway Route Designations Change Jan. 1 |newspaper=Evening Recorder |date=December 9, 1948 |agency=Associated Press |location=Amsterdam, NY|page=19}}

On April 1, 1980, ownership and maintenance of NY 239 was transferred from the state of New York to Erie County as part of a larger highway maintenance swap between the two levels of government.{{cite web |author=New York State Legislature |author-link=New York State Legislature |url=http://public.leginfo.state.ny.us/menugetf.cgi?COMMONQUERY=LAWS |title=New York State Highway Law § 341 |access-date=May 22, 2009}} The NY 239 designation was removed on September 25 of that year.{{cite book |url=https://www.dot.ny.gov/divisions/operating/oom/transportation-systems/repository/2017%20tour-bk.pdf |title=Official Description of Highway Touring Routes, Bicycling Touring Routes, Scenic Byways, & Commemorative/Memorial Designations in New York State |author=New York State Department of Transportation |author-link=New York State Department of Transportation |date=January 2017 |format=PDF |access-date=January 9, 2017}} The highway is now designated by Erie County as CR 578.{{cite map |url=http://gis.ny.gov/gisdata/quads/drg24/dotpreview/index.cfm?code=r11 |title=Cowlesville Digital Raster Quadrangle |publisher=New York State Department of Transportation |year=1998 |scale=1:24,000 |access-date=May 22, 2009 |archive-date=March 4, 2016 |archive-url=https://web.archive.org/web/20160304053819/http://gis.ny.gov/gisdata/quads/drg24/dotpreview/index.cfm?code=r11 |url-status=dead }}
