In “Notes from the Field” (Spring 1986), you write, “New York City’s Holland Tunnel, completed in 1927, was the first of many built using compressed air.” I believe there were accounts of sandhogs being blown up to the surface of the East River during the construction of the IRT and BMT tunnels well before the twenties.
Emma Cobb replies: Correct. The Holland Tunnel was the first automobile tunnel so built.
