Abandoned Freeways

[vdeane]

Recently learned about an abandoned highway that inexplicably was given an NJ state highway number instead of just fading into the abyss - NJ 324.

Well, it still faded into the abyss - I haven't been down to visit yet, but apparently it's now unsigned and mostly abandoned. It was the old alignment of US 322 to the ferry across the Delaware River (hence the "324"  designation - someone at NJDOT was being cute) before the Commodore Barry Bridge was opened and it and the new approach took 322 with it.

Do enhanced tenth mile markers count as signed?  Because I believe it has those.
