From National Historic Registry documents (Sept. 1977): The West tunnel, the shorter of the two, was originally 440 feet long but has eroded to its present 410 foot length. The steep slope on either side of the east portal has been faced with a stepped cut retaining wall. The east and west ends of the west tunnel are reinforced with concrete portals. The rail bed rests on a rock-ballast floor flanked by guttering. On either wall, cut stone wainscoting rises approximately five feet. Because of the occurrence of shale deposits in the walls, engaged piers line either side of the tunnel to provide additional stability. These piers are constructed of cut stone, brick, or concrete. They rest either on the wainscoting or on pedestals and are spaced approximately 12 feet apart. The tunnel is about 15 feet wide and 16 1/2 feet high in the center. The ceiling is limestone cap-rock and is slightly arched.
