Connecting the island of Manhattan and Jersey City at Interstate 78 is an under-river highway known as the Holland Tunnel. Initially since it is more affordable as well as easier to build a bridge rather than a tunnel, government officials first considered this possibility. However, due to the sheer number of water vehicles crossing the Hudson River, it was ultimately decided to construct a tunnel in the end.

Construction started in 1920 and ended in 1927, the tunnel was named after its chief construction engineer, Clifford Milburn Holland. Today the tunnel is being utilized by millions of traffic yearly, even though there was a slight restriction due to the attacks in 2001. The tunnel was listed as a National Historic Civil and Mechanical Engineering Landmark in 1982. Finally in 1993, it was also listed as a National Historic Landmark.
