 The route passes under a bridal path and winds southeast through the reservation (known locally as the "S Curves"), becoming the border between South Orange to the north and Maplewood to the south as it leaves the South Mountain Reservation and enters residential areas.A $30 million project to rework the "S curves" for safety and drainage is in progress.CR 510 becomes undivided again as it fully enters South Orange and continues east through wooded areas of homes, forming a brief concurrency with CR 577.
