The Starwood Apts. at 321 West 55th Street was built in 1907. Over the years, it has been the residence of theatrical figures such as Tony Award winners Jane Alexander (former head of the National Endowment for the Arts) and Michael Stewart, librettist of Hello, Dolly!
The road crosses a pedestrian island separating 12th Avenue from the West Side Highway (one of the few places where 12th and the West Side Highway are not the same). The route concludes at the West Side Highway (New York Route 9A). Opposite the intersection is the Hudson River Park and Hudson River.
