# Glen Cove Road

Glen Cove Road (also known as Cedar Swamp Road, Clinton Road, Clinton Street, Glen Cove Arterial Highway, Greenvale Glen Cove Road, Guinea Woods Road, and Pratt Boulevard) is a major, 11.7-mile-long (18.8 km) north–south thoroughfare running through north-central Nassau County on Long Island, New York, in the United States.
It is the main road leading to the communities on the east shore of Hempstead Harbor.
The portion from the North Hempstead–Oyster Bay town line to the intersection with Cedar Swamp Road (NY 107) is New York State Route 900B (NY 900B) – an unsigned reference route.
From there to Pulaski Street, it is New York State Route 107 (NY 107). 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. The limited-access section of the road is ceremoniously named Sergeant Major Daniel Joseph Daly Memorial Highway, in honor of Glen Cove native Daniel Joseph Daly.

## Route description
### Hempstead to Greenvale

The alignment of Glen Cove Road starts at Peninsula Boulevard in downtown Hempstead as Clinton Street. It travels north and northeast through Hempstead, eventually entering Garden City – at which point Clinton Street becomes Clinton Road. From there, Clinton Road continues north-northeast through Garden City until its intersection with Old Country Road – at which point it enters the Town of North Hempstead, in Carle Place, and becomes Glen Cove Road.
Glen Cove Road then continues north, crossing underneath the Main Line of the Long Island Rail Road. From there, it continues north for a distance, thence curving to the northwest to its intersection with Jericho Turnpike (NY 25), to steer clear of (and cross underneath) the Meadowbrook State Parkway and the Northern State Parkway.
From there, Glen Cove Road enters Old Westbury, where the road is concurrently signed as Guinea Woods Road. Continuing towards the north and northwest, the road soon intersects Hillside Avenue (NY 25B). It then continues north through Old Westbury, running parallel to (and serving as a frontage road for) the Northern State Parkway, intersecting I.U. Willets Road a short distance north of Hillside Avenue. From there, Glen Cove Road continues north-northeast, continuing to parallel the Northern State Parkway until the latter curves to the west; Glen Cove Road continues straight.
Continuing north-northeast, Glen Cove Road soon intersects eastbound Old Westbury Road, then immediately crosses over the Long Island Expressway (I-495), thence immediately intersecting westbound Old Westbury Road. It then enters East Hills, through which it continues to travel north, eventually reaching an intersection with Harbor Hill and Red Ground Roads. It then continues north through East Hills for a distance until reaching Town Path – at which point the road enters Greenvale. From Town Path, Glen Cove Road continues north through Greenvale, soon reaching Northern Boulevard (NY 25A), veering to the northeast on the north side of the intersection. From there, the road continues through Greenvale to Back Road and the North Hempstead–Oyster Bay town line – at which point the CR 1 designation ends and the road then continues as unsigned NY 900B.
This segment was once signed as part of Nassau County Route 1 until all county route numbers in Nassau County were removed in the 1970s.

### Greenvale to Glen Cove

Soon after an intersection with NY 25A in Greenvale, Glen Cove Road becomes a four-lane boulevard and assumes the NY 900B designation – although the reference markers refer to it as NY 904. At an intersection with NY 107, the alignment assumes that route's number and name: Cedar Swamp Road. After another 1.4 miles (2.3 km) the alignment and the NY 107 designation forks to the left as a four-lane expressway known as Pratt Boulevard, while Cedar Swamp Road forks to the right as a surface street. A short distance later, NY 107 ends at an intersection with Pulaski Street, where Pratt Boulevard becomes a four-lane surface road. The road eventually ends at an intersection with Glen Cove Avenue near downtown Glen Cove.

## History

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. The current state designation for the route only includes the Clinton Road and Glen Cove Road alignment south of the North Hempstead/Oyster Bay town line, after which it becomes NY 900B and later NY 107 and CR 243. Route 900B had originally been NY 904 prior to the creation of the modern reference route system. The county route signage was removed in the mid-1970s because the county did not want to pay to replace the signs to conform to new federal standards.
The northernmost segment of NY 107, known as the Glen Cove Arterial Highway, was constructed in the mid-1960s. Built as a bypass of Glen Street, it would have served as the approach for the cancelled Rye-Glen Cove Bridge - one of two proposed bridges to connect Rye, New York with Long Island, via. the Long Island Sound.
The bridge carrying Glen Cove Road over the Long Island Expressway was named the Police Officer Michael J. Califano Memorial Bridge, in honor of a police officer who was killed nearby on the line of duty.
