Re-Inventing the Perfectly Pennsylvania Keystone Marker
Directional Marker (Cumberland County)
COORDINATES: 40.232174, -76.932202 (approximate)
SHAPE: Standard 1-sided
STATUS: This type of directional marker was once common. This one notes distances to Pittsburgh, Rochester and Ambridge.
At one time almost all “highway” signs were of this keystone shape in cast iron.
It is presumed that this marker once stood at the intersection of US 11 & US 15, just west of Harrisburg in Camp Hill, PA.
