Nope; it's just the first changeset, though I'm not sure how editing worked before the changeset system was added early on.

Hello! Thank you for mapping the last section of the Greensboro Urban Loop as being under construction. However, I'm curious as to why you completely deleted the existing highway=proposed ways, and remapped them with less detailed tagging?

Upon further investigation, you're right that the bulk of this segment isn't I-86 yet. Current signage at the I-81-NY 17 interchange to the east indicates that the I-86 section starts there heading east, but doesn't go any farther west. There is also no signage of I-86 immediately west of Binghamton, though new signage at the Prospect Mountain interchange does include I-86 everywhere, making for weird, spotty signage. The NY 7 interchange signage also features I-86, but only going west from it across the bridge.

Whoops, Source: TIGER 2016 wasn't meant to be added here.

I only did that in this one case because internally PennDOT keeps track of that portion of road as two separate one-way roads as if it were dual-carriageway, with one being SR 0011 and the other SR 8027. However, the road has no actual physical divider and is thus a single-carriageway road for purposes of mapping. If ref:penndot:forward/backward or ref:penndot:left/right are not best here, would "ref:penndot=SR 0011;SR 8027" be?

D'oh! Fixed...

I had some conflicts here because I accidentally clicked Cancel mid-upload. It finally uploaded seemingly alright with no validation errors in JOSM, but some stuff MIGHT be broken.

I was planning on having PA 8 marked as trunk up to Butler, because it's part of the NHS and has relatively high traffic counts, and even the occasional interchange. However, if this goes against common practice, I'll change it back.

Ah, the great "first."

Mid-upload my computer blue-screened and left the changeset open, partially uploaded. I tried to upload the recovered data layer (in JOSM) but got loads of conflicts, and attempts to fix them resulted in a LOT of duplicated ways/nodes. I think I got everything and the validator didn't complain, but let me know if I missed anything.
