- COUNTY: Allegheny
- SHAPE: Variant 1-sided
- COORDINATES: 40.437557, -80.057588
- MANUFACTURER: Unknown
- STATUS: Not a "Keystone" shape, yet on a typical keystone marker post. Marker notes it was provided by the Business Men's Association, perhaps as part of a program in cooperation with the old Highways Dept. A newspaper article stated that four of these were installed - a second at the Oakmont bridge, and a third at the Thornburg Viaduct, and the fourth near Crafton Heights. Only this one remains to our knowledge.
