Clifford Milburn Holland (1883-1924) was an American civil engineer best known for his work on the Holland Tunnel, which connects Manhattan, New York, with Jersey City, New Jersey. He was appointed chief engineer of the project in 1919 and played a crucial role in its design and construction.
Holland had a background in tunnel engineering, having worked on several subway and automobile tunnels in New York City. Despite suffering from heart problems, he dedicated himself to the tunnel project, often working long hours under intense pressure. Unfortunately, the stress took a toll on his health, and he passed away in 1924 from a heart attack just before the tunnel's completion.
The Holland Tunnel was named in his honor to recognize his significant contributions to its success.
