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

Traffic

The six-lane road bridge is part of Interstate 295, the shortest connection to Interstate 95 northbound or via the Cross Bronx Expressway and the George Washington Bridge provides heading west for the east of Queens and the subsequent parts of Long Iceland. She has no footpaths or cycle paths. The speed limit is 45 mph (72 km / h). Like most major bridges in New York is also the Throgs Neck Bridge toll.

Description

The planned by Othmar Ammann Throgs Neck Bridge was the first suspension bridge in New York after the collapse of the Tacoma Narrows Bridge in Washington State in 1940. Therefore Ammann chose a design that exclude any doubt of motorists on the safety of the bridge from the outset should. The rectangular, decoration -less, 100 m (360 ft) high pylons have a rather hefty as sleek and elegant look. The bridge deck is not made of thin solid-wall carriers, but from a 8.5 m (28 ft) high and 28.3 meters (93 ft) wide truss construction.

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

The two carrying cables having a diameter of 58.4 cm (23 inches) and each consisting of 10,952 galvanized steel wires, which are summarized in the air spinning process to 37 strands of each 296 wires in a hexagonal profile, is pressed by the hydraulic cable presses to round support cables and then to prevent corrosion were jacketed. They are mounted in large, concrete anchor blocks, which have a footprint of 42 x 61 m, 45 m high and weighing 154,000 tons.

History

Robert Moses, head of the Triborough Bridge Authority (TBA ), planned as early as 1945 another bridge over the East River after the 1939 Opened Bronx - Whitestone Bridge was often overloaded. However, it took more than 10 years until he was able to instruct Othmar Ammann with the planning of the bridge. Ammann was due to age long since retired from the service of the TBA and now works in his engineering firm Ammann & Whitney. Construction began in 1957 and ended with the almost shapeless opening of the bridge on January 11, 1961.
