Description
The plaque notes consultants of Clifford Holland of Holland Tunnel fame, and Ole Singstad who designed the ventilation system, including the first in the Holland Tunnel, that made long automotive tunnels possible.
This was constructed using the immersed tube method (http://en.wikipedia.org/wiki/Immersed_tube) and is thus actually not a tunnel in the sense of being dug or bored.
