Question Mark: WV-311 near White Sulphur Springs
What is now WV-311 at I-64 Exit 183 was once US-60.  In the mid-1940s, the new route through Jerry's Run was completed as Alternate US-60.  In 1947, this was commissioned as US-60 and Virginia renumbered the old section US-60 as VA-159 and an extension of VA-311.  I originally understood that the then WVSRC (State Road Commission) didn't immediately extend WV-311 into West Virginia along this section.  But I am unable to find any evidence.  Fun fact: the other section of WV-311 was originally numbered as WV-81.  That was conveniently renumbered in 1941 to match VA-311 on both ends (not all that long before I-81 was conceived).

Here is proof West Virginia directly renumbered that tiny bit of US 60 as WV 311.  Go to page 9 here of the 1947 Virginia request, which included a letter from West Virginia:

If you are not familiar with the AASHO website to see old documents, you can instead go here first, then you can search VA and route 60 and click on 1948's pdf - https://grmservices.grmims.com/vsearch/portal/public/na4/aashto/default

Many thanks.  The AASHTO website works differently than the last time I visited (some time ago).
