10 DESIGN + Buro Happold最近赢得了中国珠海十字门中央商务区大桥的初审竞赛。大桥古朴典雅的身躯联系

10 DESIGN and Buro Happold have won the international design competition for the key
signature gateway bridge for the new Shizimen Business District in Zhuhai, China.

The feature bridge is the gateway entry to south China’s new planned commercial hub
and also marks the connection of the Shizimen Canal to the Pearl River Delta.

Working together in one of their first collaborations the 10 and Buro Happold team set
out to create a simple and elegant structural solution for a bridge that would be a
visual focal point both within the Shizimen District itself and along the Pearl River
Delta coastline.
 
The winning bridge scheme proposes an undulating ribbon of structure that wraps around
the 6 lane road deck in a continuous sculptural loop form.  At low levels the loop
cradles the road deck, with the structural ribbon then soaring upwards to create 2
triangulated arch forms.

These triangular gateways, one primary and one secondary, support the road deck
over 2 separate distinct spans via suspension cables.  The primary triangulated gate is
100m in height and by diagonally crossing the deck of the bridge celebrating not only
the crossing of vehicular and pedestrian traffic, but also the meeting point of the
canal with the Pearl River Delta.

The continuity of the loop structure is visible from the opposite mainland shoreline to
the west, and appears as a dramatic free standing infinity loop.

Complex coastline conditions created an odd and asymmetric span, however we realized
that by tying 2 simple parabolic arches together in a single ribbon form we could split
the bridge into 2 simpler spans. Thereby keeping a rational structure while making a
strong formal statement, in that the bridge when reflected off the water created a
double 8 figure, a sign of prosperity in Chinese culture.

As well as the gateway bridge the team was also placed 2nd & 3rd in the competition for
two of the 4 secondary bridges crossing the canal.
