Wanderlust World Wanderlust World The Holland Tunnel (opened 1927, connecting Manhattan and Jersey City under the Hudson River) honors its chief engineer, Clifford Milburn Holland (1883–1924).
Holland died of a heart attack (exacerbated by pneumonia) in October 1924, before the tunnel's completion. His successor, Milton H. Freeman, also died months later; Ole Singstad finished the project and designed its pioneering ventilation system.
The tunnel was the world's first mechanically ventilated underwater vehicular tunnel—setting the standard for all subsequent subaqueous road tunnels.
