It's gated, so it's not necessarily a dead end road.

It's named for linking Flanders to the South and Netcong to the North.  But it also on a census line for Budd Lake / Flanders.  The speed limit (40 mph) is consistent with the other secondaries in the area (primary on US 46 is just 45 mph, and US 206 is 50 mph), I only marked it that way cause I haven't confirmed if they repainted the lines.

So it's definitely not a residential road, it's at a minimum a tertiary road.

I did confirm the entire road is public and I'm actively working on the speed limits in that area.  The next time I'm in the area during the day I'll see what the gate is about because I am pretty sure I misstagged it's access.
