I think that's right. I-86 in NY is entirely concurrent with NY-17 (although the reverse is not true), but the freeway that used to be PA-17 is now I-86 and the PA-17 concurrency has since been decommissioned.

It's also more than "a few years" ago.  PA-17 hasn't existed there for over 20 years now  *heh*

I actually drove on the NY/PA-17 Super-2 in 1996 only a couple years before it became a divided freeway.
