Alexander Hamilton Bridge in May 2008

The total length of the bridge, including approaches, is 2,375 feet (724 m). Its parallel main spans are 555 feet (169 m) long and provide 103 feet (31 m) of vertical clearance over the Harlem River at the center and 366 feet (112 m) of horizontal clearance.[5]

The bridge design included a set of spiraling ramps (officially known as the Highbridge Interchange and colloquially known as "The Corkscrew") to connect to and from the

Major Deegan Expressway (completed in 1964) and a viaduct ramp connecting to the Harlem River Drive, both of which are over 100 feet (30 m) below the level of the bridge, and access to Amsterdam Avenue.[5]

History

After the

Cross-Bronx Expressways and to accommodate the additional traffic resulting from the addition of the six-lane lower level to the George Washington Bridge.[5][7] With the Interstate designation, 90% of the $21 million in construction costs were covered by the federal government. The bridge opened on January 15, 1963.[2]

Starting in 2009, the bridge underwent a full renovation at an estimated cost of $400 million.

traffic jams created from the construction had not been as bad as local officials had anticipated, inbound delays at the Hudson River crossings increased after the project began.[9] In July 2014, Governor Andrew Cuomo announced that the bridge renovation was complete.[10]
