Although the three portals are side by side in New Jersey, the north tube portal is one block west of the other two tubes' portals in New York City. The north tube's eastern portal is near Eleventh Avenue between 38th and 39th Streets, while the center and south tubes emerge side by side at Tenth Avenue between 38th and 39th Streets. As a result, the three tubes are of different lengths. The longest tube is the center tube, which runs parallel to the southern tube. The northern tube is long. On the Manhattan side, there is an Art Deco ventilation shaft located west of 12th Avenue.
