Specific location undetermined. Rays Hill summit on the old Lincoln Highway (U.S. Route 30) is just east of Breezewood.
Bedford / Fulton County Line
These large keystones were wooden, not iron, and marked the highest points along the major cross-state highways.
Known only from the photo below, but these were a fixture of almost all the ridge summits across the state.
