The road then continues north for some distance, before turning towards the northeast, soon crossing the Long Beach Branch again at grade level, thence entering Barnum Island and meeting back up with Austin Boulevard (CR C05), turning back towards the north.

From there, it continues towards the north, soon passing over a bridge, crossing onto Long Island and entering Oceanside, shortly after which it intersects Daly Boulevard (CR C55).

The road continues towards the north for a short distance, soon intersecting Davison Avenue (CR C56) before reaching a junction one block to the north with Lower Lincoln Avenue (CR D35), at which point Long Beach Road veers towards the northeast.

[1][2] It then reaches another junction one block to the north, where Lincoln Avenue branches off towards the northwest while Long Beach Road continues towards the north-northeast and entering Rockville Centre, soon intersecting Merrick Road (CR 27) and thence Sunrise Highway (NY 27) a few blocks further north.

Long Beach Road then continues northeast and reaches Lakeview Avenue (CR D28) two blocks to the north.

[8] A 1.1-mile (1.8 km) section of Long Beach Road, between Waukena Avenue in Oceanside and Austin Boulevard in Island Park, was also widened as part of this reconstruction project.

[8] In the 1980s, Nassau County proposed reconstructing a segment of the road in Rockville Centre, so as to eliminate a dangerous curve.
