While visiting family near Bridgeport WV, I noticed that WV 279 is posted as continuing west of I-79 (
link), but the signage on where WV 279 ends west of I-79 is not clear. It looks like it ends at Route 707 before the FBI gate but there is no signage for WV 279 here (
link). The highway browser page shows WV 279 ending at I-79.
