The bridge deck is supported by a harp-style cable-stay outline. The cables support one edge of the deck, and join to eight steel masts in a fan arrangement which I previously likened to a giant skeletal hand.
I think possibly the design visualizations were a little unflattering, as now that I've seen the (nearly) finished structure, it is a much more attractive creature.
The unusual assemblage of masts arises from the formalism of the geometry. The cables create a harp arrangement in elevation (i.e. they are parallel when viewed from that angle), and are tangential in plan to the curved edge of the deck.
This creates geometry where the cables must be supported at eight detach positions in space, rather than from a single mast.
MEDIA CITY FOOTBRIDGE,MANHATTAN
It's
an asymmetric bobtail swing bridge, spanning across the Manchester Ship Canal.
It's 83m long overall, with a 63m core span. To the north, it provides right to
use to the new Media City development in Salford, the fresh home to several
departments of the BBC. On the south bank, it presently connects to the
Imperial War Museum North, but will ultimately link in to a new ITV studio
development.
