County Route 15 travels along Beacon Hill Road and West Shore Road (also known as Roslyn West Shore Road), and is maintained, in its entirety, by the Nassau County Department of Public Works.

## Route description

Starting at its northern end, County Route 15 begins in Port Washington, at the intersection of Beacon Hill Road, Main Street, and Port Washington Boulevard (NY 101). From there, it continues east-southeast through the Beacon Hill section of Port Washington, along Beacon Hill Road. It then descends from the top of Beacon Hill, makes a sharp turn to the south, and becomes West Shore Road, paralleling the western shore of Hempstead Harbor. CR 15 then becomes a divided highway and passes the North Hempstead Beach Park (also known as Bar Beach) and the Harbor Links Country Club. Continuing south, the road soon becomes undivided once again, and it soon thereafter passes the Town of North Hempstead's landfill and its solid waste management center, the Hempstead Harbor Shoreline Park, and the Seaview & Harbor Park industrial parks. Shortly thereafter, CR 15 enters the Village of Flower Hill, soon reaching the village's Harbor Village housing development and intersecting with John Bean Court. From there, CR 15 continues south through Flower Hill, passes underneath the William Cullen Bryant Viaduct (NY 25A), and then enters the Village of Roslyn immediately thereafter. Just south of the viaduct, CR 15 passes Mott Avenue (CR D63), and then intersects with Old Northern Boulevard (CR D71 / CR 7A), where it terminates.
County Route 15 is classified as a minor arterial highway by the New York State Department of Transportation and is eligible for federal aid. The route is approximately 4.02 miles (6.47 km) in length.

## History

The CR 15 designation for West Shore and Beacon Hill Roads can be traced back to 1959, when the Nassau County Department of Public Works created a numbered highway system as part of their "Master Plan" for the county highway system. This plan marked CR 15 along its current alignment. Like all other county routes in Nassau County, County Route 15 became unsigned in the 1970s, when Nassau County officials opted to remove the signs as opposed to allocating the funds for replacing them with new ones that met the latest federal design standards and requirements, as per the federal government's Manual on Uniform Traffic Control Devices.
The historic George W. Denton House is located along CR 15, in Flower Hill; it is listed on the National Register of Historic Places.
