"Fink's truss design was one of a number of early patented solutions to [the problem of how] to carry a massive, moving weight (a train) over long spans (to avoid the expense of building piers and obstructing waterways) on easily erected bridges (often in rough terrain) with good long-term economy..."
- Kent Farnow Smith, "America's Oldest Functioning Iron-Truss Bridge," 1978

One of four single-track tunnels built by the Blue Ridge Railroad, the 4,273-foot Crozet Tunnel was constructed at a time when hand drills, pickaxes, and black powder amounted to state-of-the-art tunneling technology. At the time of its completion, it was the longest railroad tunnel in the world. Envisioned and built by Claudius Crozet, a French-born educator and civil engineer, the tunnel remains a testament to his belief in advancing rail transportation even when faced with numerous difficulties.
