The first starts from Teaneck Road (CR 39) in Ridgefield Park and heads up the east side of the Hackensack River until it reaches New Milford -- where it stops cold. The second picks up in Closter, about four miles from the end of the first section, and runs across to Closter Dock Road (CR 502). I don't know what roads CR 41 was supposed to take to connect these two disparate sections.
The NJDOT straight-line diagrams inventory the northeast section of CR 41 from east to west, but I have inverted it both for consistency and to follow the direction the road would have needed to follow if it were connected.
Most of the first section of the road is signed as part of primary route 17.
