For years, I've noted the PRR overpass over I-65 near Lebanon IN (MP141), or roundly 30 miles North of Indianapolis. This overpass has had a PRR "keystone' carved in the concrete pier visible to both North and South traffic.

Now the highway is being widened, and the State is building NS a new trestle to X the highway. Soon the Keystone will be gone.

Sic transit gloria.

Gil, there's an overpass carrying what is now Florida Northern over FL route 40 in Dunnellon, and it's still marked "Atlantic Coast Line." Don't think they're knocking it down anytime soon, however.
