Surprised nobody has commented about these couple unique bridges in this area. The important thing to note is the bridge APPEARS to be unaltered. If it is indeed unaltered it is a very unusual bridge, perhaps illustrating a railroad's early and perhaps cautious attempt to experiment with concrete as a building material, while still holding on to time-tested older designs. Truly a unique design, the arch consists of:
1. Stone Voussoir
2. Brick Barrel
3. Concrete Spandrel
Not sure how often all three materials are found being used structurally as ORIGINAL details. Brick and stone alone is notable on stone arch bridges.
