The Arthur Ashe Stadium, part of the
United States Tennis Association
(USTA) Billie Jean King National Tennis
Centre in Queens, New York City, has
been the main stage for the United
States (US) Open since it was opened
in 1997.
One of the four annual Grand Slam
events, the US Open attracts sell-out
crowds during August and September
each year, but also has a reputation for
attracting bad weather. Wet conditions
have repeatedly disrupted play on the
tournament’s main stadium and now,
after years of development, a project
estimated at upwards of US$100 million
is underway to construct a free standing
retractable roof over the stadium.
As part of this project Bradken’s
Industrial Products Business was
engaged by Cast ConneX in April 2014
to produce 16 critical connection nodes
(each weighing 3,583 kilograms or
7,900 lbs) designed to support the 24
steel columns that will hold up the
stadium’s new independent roof
structure (the stadium itself was never
designed to be covered and could not
support the weight of a roof).
The nodes will house one vertical and
two diagonal columns in a tree-like
arrangement with each configuration
supported by a foundation of concrete
filled steel pipe reaching depths of close
to 50 metres. Such foundation depth is
necessary due to the boggy condition of
the soil on which the stadium rests.
Given the critical placement of these
connections in the final design and the
high level of visibility to audience

Bradken continues to show its strength as a leading
manufacturer of complex steel castings to the structural
steel market by once again partnering with Cast ConneX
Corporation to produce a series of architecturally
exposed cast steel nodes to support a new retractable
roof over the Arthur Ashe Tennis Stadium.
