NY 25C began at the intersection of Springfield Boulevard and Union Turnpike in the Queens neighborhood of Queens Village. Here, the route connected to NY 25, which entered from the west on Union Turnpike and left to the south on Springfield Boulevard. The route headed to the northeast along the southern edge of the Oakland Gardens neighborhood on the four-lane Union Turnpike, a road often recognized more by its name than by its designation. In its first few blocks, the road passed Alley Pond Park and connected to the Grand Central Parkway by way of an interchange. The route continued on, meeting the nearby Cross Island Parkway at another interchange before heading into the Glen Oaks portion of Queens. The highway continued on a northeasterly track to the New York City line, where it turned slightly eastward as it crossed into Nassau County. Now in the town of North Hempstead, NY 25C continued to follow Union Turnpike along the northern edge of North New Hyde Park to an intersection with Marcus Avenue. While Union Turnpike ends here, the route continued eastward along the two-lane Marcus Avenue toward Herricks. After several blocks, the road turned southeast to reach Hillside Manor, a neighborhood located on the border between North New Hyde Park and Herricks. NY 25C ended here at a junction with NY 25B.
History
The NY 25C designation was assigned in the mid-1930s to the portion of Marcus Avenue between Hillside Avenue and the Northern State Parkway. In the 1940s, the northernmost portion of the route was realigned to follow Union Turnpike west into Queens, where it ended at Springfield Boulevard. The section of Union Turnpike from Kew Gardens to the Nassau County line had been converted from a narrow unpaved road to a paved multi-lane highway in the late 1930s ahead of the 1939 New York World's Fair. NY 25C was city-maintained in Queens, state-maintained from the New York City line to Marcus Avenue, and county-maintained from Union Turnpike to NY 25B. The route remained unchanged until January 1, 1970, when the designation was removed. The state-maintained portion of the route's former alignment in Nassau County is now NY 900F, an unsigned reference route.
