NY considers I- and NY- routes separate, with distinct reference markers/milepoints for each.

Internally, at least.  Signage is another matter.

Interstate portions have Interstate shields, state route portions have state route shields?

I was wondering why PA 283 wasn't given the route number 300, being the state inventories it as SR 0300.  Considering that you have an interstate numbered 283 as well, and both aren't continuation of each other as PennDOT considers them separate routes unlike New York that considers interstate/ state route combinations as one continuous route.

Might as well be a different number too.

PA 283 functions as a continuation of I-283. That number was chosen to reflect it.

They also have unified mile markers and exit numbers (well, except NY 481, but that's a recent development and I-481 is going away).  Having grown up in the part of the state where routes are just "390", "490", and "590", I'm not even sure how many people even process that there's a significance to the shields being different.  Even around Albany where everything is "interstate" or "route", NY 787 is still referred to "I-787" frequently.

But I-787 crosses the Collar City Bridge... :>

Does anyone know if there were ever any plans to build a southern bypass of Sharon? Just over the state line in Ohio, OH 82 take a sharp SE turn before it ends in a cloverleaf at US 62. The I-376 freeway from Pittsburgh ends at PA 18 southeast of Sharon, and then continues NW into Sharon proper as PA 760 and PA 718.

Both of these are logical endpoints for their respective routes, but they also look like a gap that could plausibly be connected as an alternative route (with US 422) between Pittsburgh and Cleveland.

I remember reading or hearing long ago that the eastern section of OH-82 you referenced was once considered as a plausible alternative corridor for I-80.  But the way both roads you describe turned out, you'd have to think there had been some coordination between Ohio and Pennsylvania DOT's (in the late 50's/early 60's) to have their endpoints line up so as to potentially connect at some future time.

However during that era there were steel mills and other thriving industrial facilities smack dab in the middle of the route that would connect the two roads, not to mention the low-lying wetlands and the Shenango River which snakes through that area ~ which would make construction of a connecting freeway an engineering challenge to say the least.

The OH-82 / US-62 cloverleaf interchange in retrospect was overbuilt as planners apparently assumed the booming steel industry facilities nearby would continue forever.  And in some respect the cloverleaf interchange at I-80 / I-376 (formerly PA-60) could also be looked at as overbuilt (or underbuilt ?) with 1960's-era tight turn radius with short merge / weave stretches.
