I noticed this today when zooming in on our VA map around DC. There seems to be two different George Washington Parkways. They seem to have the same waypoints between I-495 and I-66. But, then the first one goes on for about another 5 miles while the second ends at DC/VA. I was wondering what the difference was.
(George Washington Parkway)
.list name: VA GeoWasPkwy
14.03 miles
Green sign
(George Washington Memorial Parkway (Langley))
.list name: VA GWMemPkwy
9.05 miles
Brown sign

The Green sign one was made a decade ago (and probably not changed since) and is in the active 'Select Named Freeways' system.
The brown sign one was made later and is in the preview 'National Park Highways' system.
The Green one ignores the border and continues on, while the brown one is chopped.
I'm not sure they are even concurrent - the Green one ought to be chopped and synced with the brown one - and when usanp becomes active, removed.

The reason for the disparity is because there is a section of the George Washington Parkway that technically is within the District of Columbia. However, when the select named freeways system was created, it was decided to keep everything on that side of the Potomac River in Virginia for simplicity.
Personally, I think it should still stay that way, but whomever created the National Park Highways lists clearly disagrees with that.

If we wanna "stay that way", I think we can close the issue.

No objections, marking solved.
