The first section extends from Maple Avenue in Ridgewood across to the corner of Lafayette and Washington avenues in Westwood. The second section starts at Kinderkamack Road and Westwood Avenue in Westwood and runs east to the state line at Old Tappan. The obvious connection is CR 502 to the corner of Washington Avenue, Broadway, and Westwood Avenue, and then CR S-114 to Kinderkamack Road. (Some maps list CR 110 on that three-block stretch of Westwood Avenue in downtown Westwood.) I have taken the liberty of calling it a “secret multiplex”, and including its mileage in this log.
The stretch of Old Tappan Road from Washington Avenue to Orangeburgh Road is part of primary route 17.
