The 9th Ave El was over 100 feet above the street at "Suicide Curve", which made a 90-degree turn from 9th Ave onto 110th St. then another from 110th St. onto 8th Avenue. The line ran along 9th and Columbus Avenues in midtown and upper Manhattan, and Greenwich Street in lower Manhattan, and ran until it was closed in 1940 and dismantled, following the purchase of the IRT by the City of New York. The line from 155th Street north into the Bronx was continued as the "Polo Grounds Shuttle" until 1958.
Also: in 1927 the New York Times reported that 11 people had jumped to their deaths from the station. Merchants complained it was souring business and people avoided the area at all costs. More here.
