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 linear path for a half-mile to an intersection with the
Little Neck Parkway. Upon crossing the parkway, the structures along Hillside Avenue shift from residential to commercial, a trend that remains in place to the
Nassau County line. The commercial presence continues for two blocks eastward before shifting back to residential structures. The four-lane NY 25B, along with a separate, parallel Hillside Avenue South, continue eastward through blocks of primarily homes to Herricks Road, where the composition of structures along NY 25B becomes a mix of commercial buildings and residential dwellings once more. Hillside Avenue continues on, entering
Williston Park. On the eastern edge of the village, NY 25B narrows to two lanes as it
crosses the
Oyster Bay Branch of the
Long Island Rail Road and enters
East Williston, where the surroundings shift to residential for the final time. In the center of the village, NY 25B intersects Roslyn Road before passing by the North Side School two blocks to the east. Roughly a half-mile from the school, NY 25B enters the village of
Old Westbury and passes over the eight-lane
Northern State Parkway with no connection between the two. The missing link is filled by way of
Glen Cove Road, which NY 25B intersects a mere from the parkway, and Jericho Turnpike (NY 25), accessible via Glen Cove Road. East of Glen Cove Road, NY 25B enters
Westbury and begins to develop a large median in preparation for an interchange with NY 25 roughly to the east. Just west of the interchange, NY 25B intersects Bacon Road. from the intersection, NY 25B crosses over NY 25 west and enters the median of NY 25 prior to merging with NY 25 east, ending the NY 25B designation. ==History==
