History

Beginning in 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, what is now CR C71 was originally designated as part of County Route 99, with Plainfield Avenue. This route, along with all of the 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 stated in the federal government's Manual on Uniform Traffic Control Devices.
Subsequently, Nassau County renumbered many of its county roads, with CR 99 being split in two: Elmont Road would become CR C71, while Plainfield Avenue would become CR D90.
