60th Street Tunnel

The 60th Street Tunnel carries the N, ​R, and ​W trains of the New York City Subway under the East River and Roosevelt Island between Manhattan and Queens.

The tunnel was built as part of the Dual Contracts, which expanded the current New York City Subway system greatly. The original plan provided for trackage over the Queensboro Bridge, which spans the East River from about 59th Street in Manhattan to Queens Plaza in Queens. However, an investigation made following the 1907 collapse of the Quebec Bridge determined that the bridge would not be able to handle the additional weight of subway trains; thus, the tunnel was constructed to the north. Clifford Milburn Holland served as the engineer-in-charge.
