My great great grandfather, CJ Schultz, had a bridge building company in Pittsburgh: The Iron City Bridge Works. He built "the Red river bridge on the Texas Pacific railroad" ("History of Allegheny County" by Cushing, p.39). This would have been in the 1870's or 80's.

Does anyone know where this bridge may have been? Is there a list of all the T&P bridges that went across the Red River?
