This volume reprints Paper No. 1154, “The Bergen Hill Tunnels,” by F. Lavis, from the Transactions of the American Society of Civil Engineers for September 1910. It is a technical engineering account of the construction of the tunnels through Bergen Hill in New Jersey, part of the great railroad works that brought trains beneath the Hudson into New York.
The paper describes the methods, materials, and challenges of the project with the precision expected of a professional engineering society, and includes discussion by other engineers. It documents a significant feat of early-twentieth-century American infrastructure. For readers interested in the engineering side of the built environment, tunnels, and the history of civil engineering, it offers a detailed primary record of a notable undertaking.
