 The road follows roughly the course of the later Delaware and Hudson Canal for its northern half, and the Delaware River in its southern half through the western edge of Sussex County and northern Warren County in northwestern New Jersey.The road exists today, and although much of its length in New York has been modernized, widened and incorporated into US 209, its length in New Jersey as the "Old Mine Road" is largely undeveloped as it travels through the Delaware Water Gap National Recreation Area.The road still retains much of its historical and rural charm.
