This segment includes the Glen Cove Arterial Highway (also known as part of Pratt Boulevard) – an expressway that was intended to connect to a proposed bridge across the Long Island Sound to Connecticut.

[3] The alignment of Glen Cove Road starts at Peninsula Boulevard in downtown Hempstead as Clinton Street.

It then continues north through Old Westbury, running parallel to (and serving as a frontage road for) the Northern State Parkway, intersecting I.U.

It then continues north through East Hills for a distance until reaching Town Path – at which point the road enters Greenvale.

[7] At an intersection with NY 107, the alignment assumes that route's number and name: Cedar Swamp Road.

A short distance later, NY 107 ends at an intersection with Pulaski Street, where Pratt Boulevard becomes a four-lane surface road.

Glen Cove Road was once (as of 1959) part of an extended County Route 1, which reached as far south as Point Lookout and as far north as Centre Island.
