Here’s some text from the architects:
Sheikh Zayed Bridge
The UAE has a highly mobile society that requires a new route around the Gulf south shore, connecting the three Emirates together. In 1967 a steel arch bridge was built to connect the fledgling city of Abu Dhabi island to the mainland, followed by a second bridge built in the seventies, connecting downstream at the south side of Abu Dhabi Island. The location of the new (third) Gateway Crossing, close to the first bridge, is critical in the develop- ment and completion of the highway system. Conceived in an open setting, the bridge has the prospect of becoming a destination in itself and potential catalyst in the future urban growth of Abu Dhabi.
A collection, or strands of structures, gathered on one shore, are lifted and ‘propelled’ over the length of the channel. A sinusoidal waveform provides the structural silhouette shape across the channel.
The mainland is the launch pad for the bridge structure emerging from the ground and approach road. The Road decks are cantilevered on each side of the spine structure. Steel arches rise and spring from mass concrete piers asymmetrically, in length, between the road decks to mark the mainland and the navigation channels. The spine splits and splays from one shore along the central void position, diverging under the road decks to the outside of the roadways at the other end of the bridge.
The main bridge arch structure rises to a height of 60 m above water level with the road crowning to a height of 20 metres above mean water level.
