Bronx-Whitestone Bridge (1939)
NThe first proposal for the construction of the Bronx-Whitestone Bridge,
also known as the Whitestone Bridge was put forth as early as 1905.
Expecting that the Whitestone Bridge plan would be approved, developers
build up the neighborhood of Malba in Whitestone. However the residents
of Whitestone opposed the building of the bridge, believing that it
would change the rural character of Queens. The project was abandoned
until 1930 when the influential NYC parks Commissioner Robert Moses
proposed a plan to build it. The proposed suspension bridge would cross
the East River and provide a vital connection between the boroughs of
Queens and Bronx. It would give thousands of motorists the ability to
avoid heavily populated areas of western Queens, when traveling between
Long Island, New England or upstate New York. The New York State
legislature approved the plan for the Whitestone Bridge in April of
1937. The Whitestone Bridge not only relieved the congestion on the
Triborough Bridge but also provided easy access to LaGuardia Airport
(then known as North Beach Airport). As the chairman of the 1939-1940
World’s Fair, it was equally important to Robert Moses that the bridge
provide a direct link to the World’s Fair.
As soon as the necessary approvals were granted, Robert Moses
apportioned Othmar Ammann as the chief architect. The pair had worked
together on the Triborough Bridge and would continue to collaborate on
several projects throughout their lives. Opposition to the building of
the Bridge surfaced when Robert Moses made a controversial decision to
demolish 17 homes in Malba to speed up construction. Robert Moses was
also challenged by the Regional Plan Association (RPA) who insisted that
the plans for the Whitestone Bridge make provisions for rail transit.
However, the RPA was not able to generate enough pressure to influence
the guidelines for construction.
The deadline for the Whitestone Bridge was set for the opening of the
1939 World's Fair in April. The lack of time incentivized both Robert
Moses and Othmar Ammann to complete the bridge in record time; the
Bridge was complete in a mere 23 months. Othmar Ammann had an incredible
ability to work around budget and time constraints without compromising
the quality of his work. With the tight construction schedule given to
him by Robert Moses, Othmar Ammann was able to cut the construction time
in half by implementing innovative measures. One of these measures was
to abandon the traditional use of stiffening trusses, and use a flexible
steel-plate girder to reinforce the bridge. This decision was highly
controversial at the time since a similar bridge in Washington State,
called the Tacoma Narrows Bridge, had collapsed during a storm in 1940.
The Tacoma Narrows Bridge also used a similar type of the steel-plate
girder as reinforcement. Shortly after the opening of the Whitestone
Bridge, questions were raised about its safety, and many questions
addressed concern with the bridges ability to withstand high winds.
After closer inspection it was discovered that the bridge had a
fundamental flaw in its design: during high winds it was prone to
oscillation, deeming it unstable.
In 2001, $286 million was put forth by the MTA Bridges and Tunnels to
address this issue and to further rehabilitate the bridge; the
rehabilitation process was completed by 2008.
