SC 64-Y: Appeared by 1940 as a new primary route, running from SC 64 (now US 17 ALT) Round O north 0.2 miles towards Sidney.
 By 1943, SC 64-Y was decommissioned.  Today it is S-15-45. This is a weird one...the other Y route I am aware of that was a spur was eventually turned into a longer state route (SC 171Y became SC 667).
