The Throgs Neck Bridge is a suspension bridge over the East River in New York City that connects the Throgs Neck neighborhood in the Bronx with the Bay Terrace neighborhood in the borough of Queens on Long Island . It is the third bridge connection between Queens and the Bronx after the Triborough Bridge / Robert F. Kennedy Memorial Bridge and the Bronx-Whitestone Bridge .

location

The Throgs Neck Bridge is located at the eastern exit of the East River into Long Island Sound . From the south, a curved ramp bridge leads over Little Bay to the suspension bridge over the East River. On the northern side of the suspension bridge, a long ramp bridge leads in a large curve over the Throgs Neck and a shallow bay on its northern side. The bridge is about 17 km as the crow flies from Manhattan , whose skyline is visible on a clear day.

traffic

The six-lane road bridge is part of Interstate 295 , which provides the shortest connection to Interstate 95 north or the Cross Bronx Expressway and the George Washington Bridge to the west for east Queens and the subsequent parts of Long Island . It has no sidewalks or bike paths. The speed limit is 45 mph (72 km / h). Like most major bridges in New York, the Throgs Neck Bridge is a toll road .

description

The Throgs Neck Bridge, planned by Othmar Ammann, was the first suspension bridge in New York after the collapse of the Tacoma Narrows Bridge in Washington State in 1940. Ammann therefore chose a design that would rule out any doubts that motorists had about the safety of the bridge from the outset should. The rectangular, unadorned, 100 m (360 ft) high pylons have a stocky rather than slender and elegant appearance. The bridge deck does not consist of thin solid wall girders , but of a 8.5 m (28 ft) high and 28.3 m (93 ft) wide truss construction .

The bridge has a length of 4,084 m (13,400 ft) including the long ramp bridges. The actual suspension bridge is 887 m (2,910 ft) long, measured from anchor block to anchor block, has spans of 548.6 m (1,800 ft) in the main opening and 169 m (555 ft) in the side openings and a clearance height in the middle from 43 m (142 ft) above MHW .

The two suspension cables have a diameter of 58.4 cm (23 inches) and each consist of 10,952 galvanized steel wires, which are air-spun into 37 strands of 296 wires in a hexagonal profile, pressed by hydraulic cable presses into round suspension cables and then to prevent Corrosion coated. They are fastened in large, concrete anchor blocks, which have a footprint of 42 x 61 m, are 45 m high and weigh 154,000 tons.

history

Robert Moses , head of the Triborough Bridge Authority (TBA), planned another bridge over the East River as early as 1945, after the Bronx-Whitestone Bridge , which opened in 1939, was also frequently overloaded. However, it took more than 10 years before he was able to commission Othmar Ammann to plan the bridge. Ammann had long since retired from the service of TBA due to his age and now works in his engineering office Ammann & Whitney. Construction work began in 1957 and ended with the almost informal opening of the bridge on January 11, 1961.

toll

The bridge is subject to a toll . The costs for this in 2018, for a two-axle car, amount to 8.50 US dollars for payment on account or 5.76 US dollars with the E-ZPass . Like all bridges in New York City, the Throgs Neck Bridge has been "cashless" since 2017. This means that it is no longer possible to pay the toll directly. If there is no EZ pass in the vehicle, an invoice will be sent to the vehicle owner.
