Creation: Appeared about 1990 as a renumbering of part of WV 9. It originally ran from the new US 340 freeway through Charlestown to the new WV 9 bypass north of Ranson. This is the only WV 115.
Adjustments: About 2007, WV 115 was extended north to WV 480 Kearneysville, mostly over more WV 9 though there was some new alignments to maneuver around interchanges, etc., especially from CR 9/1 Currie Rd to CR 8 Wiltshire Rd. where it is unclear if WV 115 follows War Admiral Rd (shown on Jefferson County map even though it is posted as CR 9/50), duplexes with WV 9 (not posted there either), or is in separate pieces.
About 2010, WV 115 was extended north over more WV 9 then west over new construction back to WV 9 in Berkeley County.
In November 2012 (aaroads forum), WV 15 was extended south over WV 9 in the other direction to the new WV 9 alignment at the Virginia State Line.
Improvements: Upon designation, WV 115 was fully paved; WV 115 has no multilane segments
Comment: WV 115 does not seem to be posted between US 340 and the Virginia State line - there is a reassurance shield leaving US 340 and that is it.
Not sure why it is necessary for WV 115 to exist north of the WV 9 jct past Ranson.
WV 115 is shown but not labeled on official tourism maps but is shown on a different kind of state map on WVDOT's website
