The road starts from CR 84 and uses Godwin Avenue, Ridgewood Avenue, and Oradell Avenue to get to Kinderkamack Road. Logically, the road would continue on Oradell Avenue and then turn left into Haworth, but there is a stretch of roadway that is not county-controlled, leaving CR 80 in two broken sections. A 1959 County Planning Board map shows that this stretch was county-controlled at that time.
A funny thing happened when they built the Garden State Parkway. Ridgewood Avenue got eaten by the Parkway right-of-way for a little more than half a mile. To compensate, Oradell Avenue – which started from Ridgewood Avenue – became directly connected. This is reflected in the log below.
The 6.18-mile stretch of CR 80 from Lake Street to Kinderkamack Road is signed as part of primary route 6.
