New York State Route 25B (NY 25B) is a east–west state highway located on Long Island in New York, United States. The western terminus of the route is at an intersection with NY 25 in Queens. The eastern terminus is at an interchange with NY 25 in Westbury, Nassau County. NY 25B is named Hillside Avenue for its entire length, except for a brief portion in the village of East Williston, where it is called East Williston Avenue. The route, assigned in the mid-1930s, acts as a northern alternate to NY 25, running parallel to its parent for its entire length. Unlike NY 25, which is four lanes wide for most of its length between Queens and Westbury, NY 25B has a number of lane configurations, including six lanes in Queens, four lanes in western Nassau County, and two lanes in East Williston. The route also connects NY 25 to the villages of Williston Park and East Williston. Route description NY 25B is maintained by the New York City Department of Transportation (NYCDOT) within Queens and by Nassau County within the village of East Williston, where the route is co-designated but not signed as County Route 85. The remainder of the route is state-maintained. Queens Hillside Avenue changes designations from NY 25 to NY 25B at an intersection with Braddock Avenue in the Queens neighborhood of Queens Village. Here, NY 25 turns right onto Braddock while NY 25B begins and follows Hillside Avenue to the northeast. The road, a six-lane divided highway with a large, tree-lined median in the vicinity of the junction with Braddock Avenue, begins to narrow after intersecting 229th Street, passing the Martin Van Buren High School as the median is reduced to a single turning lane. At 232nd Street, the street turns to the east for three blocks before curving to the southeast at Winchester Boulevard. The lane composition of NY 25B remains the same as it proceeds eastward through heavily residential areas of Queens, maintaining a width of six lanes with a turning lane acting as the divider between opposing traffic. Roughly from Winchester Boulevard, NY 25B, facing northeast once more, intersects the west (southbound) frontage road of the Cross Island Parkway in Bellerose. Shortly after passing over the six-lane parkway, Hillside Avenue meets the eastern (northbound) frontage road. East of the parkway and surrounded by homes once again, NY 25B heads northeast on a
