Please revert. I-80 as a whole does not presently carry the name "Keystone Shortway" in Pennsylvania and has not for a long time. That name was historically used in legislation, planning, advocacy, and construction. But that name fell off decades ago. The official_name that is already on the relation and ways has been the sole official name since 1984. In the 21st century, "Keystone Shortway" is not in common use, I am aware of zero signage with that name, and very few Pennsylvanians would have any idea what highway that name is referring to. There MIGHT be a few segments of I-80 where the name Keystone Shortway is used in at least an administrative context, possibly in Clarion County--but again, not statewide. Overall, Wikipedia is simply incorrect here - note that it that it cites zero sources for any modern relevance of this name.

The PGC themselves call the access road into SGL57 from the intersection with 487 "Mountain Springs Road," as do locals who hunt, bike, and hike SGL57. Please elaborate on how that name is "garbage" and what you saw in a ground survey that contradicted this.
