Route description
CR C52 begins at Hempstead Turnpike (NY 24) in Elmont, across the intersection from Meacham Avenue (CR D49). From there, it travels Northwest to Harrison Street, where it meets the Covert Avenue Spur (CR C52). From there, Covert Avenue turns to the north-northeast, continuing in that general direction for a distance, and then turns to the north-northwest, intersecting Reed Avenue. From there, CR C52 continues north-northwest to Tulip Avenue (CR E41), which it intersects adjacent to Sewanhaka High School. From there, Covert Avenue enters the Incorporated Village of Stewart Manor and turns to the north-northeast, forming the border between that village and the Incorporated Village of Floral Park. It then continues north-northeast, eventually crossing the Long Island Rail Road's Hempstead Branch at-grade. On the north side of the tracks, CR C52 forms the border between the incorporated villages of Stewart Manor and New Hyde Park until reaching Stewart Avenue (CR 177).

North of Stewart Avenue (CR 177), Covert Avenue enters the Incorporated Village of New Hyde Park, continuing north-northeast for a distance before curving to the north-northwest. CR C52 then crosses underneath the Long Island Rail Road's Main Line and continues north-northwest to its northern terminus at Jericho Turnpike (NY 25).

Covert Avenue, in its entirety, is classified as a minor arterial road by the New York State Department of Transportation.

History
Covert Avenue was formerly designated as part of CR 174, with Meacham Avenue, prior to the route numbers in Nassau County being altered. It, like all other county routes in Nassau County, 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.

In 2019, Covert Avenue's grade crossing with the Long Island Rail Road's Main Line was eliminated, as part of the Long Island Rail Road's Third Track Project. As part of the associated reconfiguration of Covert Avenue and the construction of its underpass, the road now passes underneath 2nd and 3rd Avenues, with one slip lane connecting to 2nd Avenue and another connecting to 3rd Avenue. The grade crossing elimination project required a six-month closure of that stretch of Covert Avenue, during which time the crossing was removed and the underpass was installed.
