Park Avenue Area on a Sunday Morning

 


Between 33rd Street and 40th Street, the left-hand northbound lane descends into the Murray Hill Tunnel. Immediately across from 40th Street, the center lanes of Park Avenue rise onto an elevated structure that goes around Grand Central Terminal and the MetLife Building (formerly the PanAm Building), carrying each direction of traffic on opposite sides of the buildings. The bridge, one of two structures in Manhattan known as the Park Avenue Viaduct, returns to ground level at 46th Street after going through the Helmsley Building (also referred to as the New York Central Building or 230 Park Avenue). The IRT Lexington Avenue Line runs under this portion of the street. Once the line reaches Grand Central, it shifts east to Lexington Avenue.
