Since the news release states that PA 297 signs should be up as early as next week, I am going to go-ahead and change the route number in the HB tonight.

When I drove this back in August, the segment markers had already been changed from SR 295 to SR 297.

In case someone thought that I jumped the gun and made the change too early, PA 297 is already posted (minus the guide signs on I-83).

Verified in the field on my trip from the DC FedroSplat to eastern PA this evening. (I also clinched what is now PA 297, which I'll get into github later this week with my other new stuff.)
