PA: PA 347 Extension to Green Ridge St (SR 6011)

I found out today that PA 347 was extended south to the Green Ridge St (SR 6011) intersection.  This was confirmed by the VideoLog and the SLDs.  This should be in the HB within the next week.

I also broke the graph connection with US 6 BUS as the current connection is via a connector road (Hull's Creek Rd) and marked the old points there as closed at an older ramp connection showed via Historic Aerials (2005).

After further consideration, I restored the graph connection here.
