There is a short gap in the road due to the interchange of NJ 4 and NJ 208, and it is impossible to follow the road northbound without cutting over to Paramus Road (CR 62) and making a U-turn on NJ 4. However, a southbound connection is possible.
Between NJ 4 and the Prospect Street/Ackerman Avenue split, CR 79 is part of primary route 9.
