The Triborough Suspension Bridge has a 1380 ft long main span. It was designed by Othmar Ammann and completed in 1936. It is part of the 'Y' shaped Triborough Bridge Project which includes a lift bridge over the Harlem River and a truss bridge over the Bronx Kill, a narrow strait separating Randall's Island from the Bronx. This project was originally owned by the City of New York, but it was transfered to the Triborough Bridge and Tunnel Authority in 1933.
North of the Triborough Suspension Bridge is the Hell Gate Arch Bridge, a railroad bridge with a 1017 ft main span. It was designed by Gustav Linderthal and completed in 1917.
