From there, it enters the Village of Roslyn, and it descends and winds its way down to its intersection with West Shore Road (CR 15).

[4][6][7] It then veers back to the east to get to the east side of Hempstead Harbor and the Roslyn Creek, crossing the Mill Dam and passing through the Roslyn Village Historic District, eventually reaching an intersection with East Broadway (CR C65) in front of the Roslyn Savings Bank Building; this marks the eastern terminus of the CR D71 designation, which is superseded by the CR C65 designation from here to the eastern terminus of Old Northern Boulevard.

It then proceeds northeast, merging into eastbound Northern Boulevard (NY 25A) just west of Sinclair Martin Drive.

[4][5][6][7] Old Northern Boulevard was historically part of the Flushing and North Hempstead Turnpike (modern-day Northern Boulevard) – a major toll road linking Flushing and points west with North Hempstead (including Roslyn) and points east.

[8][9][10][11] Upon the opening of the Bryant Viaduct, NY 25A was shifted onto the new highway, and the original stretch through Roslyn became known as Old Northern Boulevard.
