Lest you think that I'm only fixated on the bridge across the Ohio (yeah, we all know the truth. 
), here are some photos of culverts and bridges on the PRR Panhandle from the river towards Colliers, WV.
Below is Harmon Creek and in the background, what used to be the center of the Revolutionary-era village of Holliday's Cove, WV. In the foreground is the bridge (automobile) across the creek that led from Holliday's Cove to Colliers, WV.
Better shot of the bridge abutment.
That road to Colliers went under the Panhandle at what was commonly called "the rat hole", a narrow tunnel or culvert originally built to accommodate horse-drawn wagons and later Model T sized automobiles. It was used well into the 20th Century by cars until a new road was built and the property was acquired by the lumber yard.
At that point, the "rat hole" was partially filled in (floor was raised) and dedicated to drainage use.
Note the Pennsy hairpin railings.
The "Standard Railroad of the World" had standard handrails.
This is the Panhandle roadbed looking east towards Colliers, WV and Burgettstown, PA. It is now a rail trail.
PRR Panhandle looking west.
There is a Geodetic survey marker here atop the culvert.
Further east is another bridge across Harmon Creek. I refer to it as "the three arches" - it doesn't have a real name as far as I know. Harmon Creek originates in Pennsylvania and flows into the Ohio River at Holliday's Cove (roughly east to west). It parallels much of the Panhandle at this point.
The "three arches" bridge is constructed of stone, as older photographs prove. Some time ago, the stone was faced with concrete, but you can still see the underlying stone here and there.
We didn't actually visit here on this trip, but I thought I would include it for completeness. To get here, you would travel east through the village of Colliers (on the "new" road). Just on the other side of bridge, the pavement becomes gravel.
Hope you enjoyed the travelogue.

I'm sure your models will look as good as the real thing
