The bridge was conceived in the early 1900s as a way to link New York and the Pennsylvania Railroad with New England and the New Haven Railroad.
(originally the New York Connecting Railroad Bridge or The East River Arch Bridge) is a 1,017-foot (310 m) steel through arch railroad bridge between Astoria, Queens and Randall’s Island in New York City, over a portion of the East River known as Hell Gate.
The engineering was so precise that when the last section of the main span was lifted into place, the final adjustment needed to join everything together was 1⁄2 inches (12.7 mm).
This bridge was the inspiration for the design of Sydney Harbour Bridge
