I'm not a fan of the bolded and un-abberviated WV 48, as well as the repeated uses of WV 480.
I left the un-abbreviated WV 48 because that is the verbatim redirect. I removed one of the WV 480 mentions so it is mentioned at most every other sentence unless necessary to avoid ambiguity. VC 01:26, 10 October 2018 (UTC)[reply]
"throughout its length" could be moved to the beginning of its sentence and replaced with a better word.
"The entire length of the highway was paved in the mid-1920, including a different routing..."
Mention how close the WV 9 interchange is (even without using actual length, perhaps "nearby interchange" or "a short distance southwest through")
I changed "an interchange" to "its interchange," but I do not think we need to quantify or qualify how close the interchange is to WV 480's terminus. VC 01:26, 10 October 2018 (UTC)[reply]
"Historic home Rockland" should be reordered as either "historic Rockland home" or "historic home named Rockland"
The width and paving could be moved before "northern extension" to make it a bit less of a mouthful.
I simplified the sentence by moving the year to the front. I could not combine the width and paving info with the extension part. VC 01:26, 10 October 2018 (UTC)[reply]
"US 48 was assigned to the freeway between Morgantown and Cumberland that later became part of Interstate 68." could be compressed into "US 48 was assigned to the Morgantown–Cumberland freeway hat later became part of Interstate 68."
It has been four weeks since this was opened, and the most recent Wikipedia edit from the nominator, Viridiscalculus, was one month ago when they nominated the article to be a GA. SounderBruce, if the issues aren't addressed soon, perhaps the nomination should be closed. BlueMoonset (talk) 13:59, 9 October 2018 (UTC)[reply]
