My research shows that some structures were built along the South Pennsylvania Railroad between Harrisburg and Donegal, Pa. Besides what most people know of the stone piers in the Susquehanna River is the bridge abutments on the Stony Creek crossing just north of the Pennsylvania Turnpike and the other well known Geiger Culvert over the B&O Railroad north of the town of Somerset. I have also photographed well dressed culverts along the whole route. Has anyone else explored these structures beneath their favorite railroads?
