110th Street Curve, also known as “suicide curve,” 1913.

In 1879, the elevated tracks of the IRT Ninth Avenue Line were extended northward from the 104th Street station. At 110th Street, the trestle turned 90 degrees to the right on 110th Street, before turning uptown again at Eighth Avenue.

The 110th Street station and adjacent tracks earned the nickname “suicide curve,” as the high elevated railway had become a destination for jumpers. In 1927, the New York Times reported that local business owners were concerned that the curve’s reputation was a deterrent to customers. The Ninth Avenue El ceased operations in June, 1940, and the railway was dismantled shortly thereafter.

While many sources claim the tracks stood a dizzy 100 feet above street level, a 1940 dispatch in the New York Times quoted the project superintendent overseeing the trestle's demolition, who claimed a maximum height of 56 feet.

Today, the elevated tracks former right of way is still visible at the southeast corner of 110th Street and Columbus Avenue: older buildings are set back from the corner, while more recent single-story construction occupies the land once underneath the tracks.
