I was looking at a PA state tourist map and saw that there is a Bus I-376 in Allegheny County. When did this come about? How well is this signed. Is the BUS LOOP I-83 still around in York, PA?
Business Loop I-83 is alive and well:

Business Loop I-376 was designated on November 6, 2009:

I-376 in that area used to be PA 60, and the business route was Bus PA 60. When the I-376 designation came, so did Bus I-376.
So...further north to Mansfield PA, when the US 15 freeway becomes I-99, will Bus US 15 become Bus I-99? And will everyone be green with envy over a green I-99 shield??? :)
Here's one of the Business I-376 route markers, photographed near the Pittsburgh airport.

Is Pennsylvania the only Northeastern state that has "business" Interstates?

Yes, but there were two others posted at one point:
Business Loop I-89 at Lebanon, NH (http://www.interstate-guide.com/business-routes/bus89.html) and Business Spur I-495 into Lowell, MA (http://www.interstate-guide.com/business-routes/bus95.html).
There is also Spur I-270 (https://www.aaroads.com/guide.php?page=i0270smd) and Spur I-895 in Maryland (https://www.aaroads.com/guide.php?page=i0895smd), but they are not Business Routes.
Additionally "Interstate 495X" exists in Maryland, which is an unsigned connector along Cabin John Parkway outside D.C.

Aww, crap. I guess that means I don't have Maryland's interstates clinched after all. :angry: :ded: :banghead:
I think CT had a Bus I-95 Spur in the New London / Groton area???

Forgot about that entry from Michael Summa, you are correct:

QuoteThere was also a BUS-SPUR 95 signed in CT (in the early to mid-1970s) at or near Mystic.
