23rd Street station (PATH)

[3] This PATH station has two side platforms, but passengers must descend one level, walk through an underpass, and go up another stairwell, leading to the New York City Subway mezzanine.

[4] There is a connection to the Sixth Avenue Line at their platforms, served by the F, , and ​M trains, which surround both sides of the PATH station.

[4] The express tracks were constructed in the mid-1960s using the "deep-bore" tunneling method and both are not visible from the station.

[5] On the express tracks on the lower level, the deep-bore tunnel's round shape becomes square below this station and at 14th Street stations, where provisions for lower level platforms were built.

There are two exits to each corner of that intersection, which serve both the subway and PATH platforms in each direction.
