NJ: NJ 19 southern end is incorrect

[mapmikey]

NJ 19 does not directly go to the GSP...it continues south along Broad St to end at Colfax Ave, which is the southernmost ramps from US 46.

Fully posted to begin/end there...

The southbound end signage until recently was a blank/extremely faded shield...

NJDOT shapefiles and this map agree:

Point labeling may also be an issue. What is & is not CR509...

[yakra]

Every label referring to CR509 does in fact refer to CR509.
I chose to reuse the (in-use) CR509_CliS label rather than just hide it behind GarStaPkwy as an AltLabel. The hit to the interpretation of anyone's list file should be minimal.
