Spur CR 577

[dgolub]

I was poking around Google Street View and noticed that the section of Prospect Avenue in West Orange, New Jersey, between CR 508 and where CR 577 comes in is signed as Spur CR 577.  However, I don't see this route included in the straight line diagrams.  Does anyone know what the deal is here?  Was it decommissioned very recently since the photos were taken, or is it just yet another SLD error?

Looking at some old maps of New Jersey, Prospect Avenue in West Orange looks to be just 577, not Spur 577. Steve has this written on the CR 577 page:

Signage on SB Prospect Ave./CR 577 approaching the very beginning of NJ 10. This includes the incorrect signage for Spur CR 577, which was de-designated years ago and is rightly CR 677. I guess it's really whatever Essex County wants it to be, since it doesn't cross into any neighboring county, but NJDOT really ought to go along with any 500-route changes, and they haven't. I'm not sure if the first and second photos were taken in the same place, but I think they were, meaning that signage for the only state highway at the intersection has been removed, leaving more of the only error.

Spur 527 is still signed from NJ 124, but fortunately every other reference has been corrected. (Hobart Gap Rd./White Oak Ridge Rd. and thence to Livingston Ave. along 649) Spur 577... it's short enough that I don't much care. Spur 509 has interestingly never been signed although still technically "on the books" - always shown as 577.
