The square US 340 marker and a small, easily missed sign nearby, are the only indications of traveling northbound on US 340 through a small slice of Virginia, between West Virginia and Maryland, near Harpers Ferry, West Virginia. I had originally thought this was in West Virginia. After posting this photo in a group on Facebook, several other group members pointed out that the square marker along with the destination sign, were a standard Virginia sign assembly. Thanks to H. B. Elkins, Brian Powell, and C. Patrick Zilliacus for the correction and additional information.
This photo was taken in June 2013. The destination sign is for Frederick, Maryland, which is the northern terminus of US 340.
