ARCHITECT: Zaha Hadid ArchitectsPROGRAM: 2 ways four lane highway bridge.MATERIALS: Piers, Decking: Pre-stressed/Reinforced Concrete Arches: Steel

The length of the bridge is 842 meters.The bridge consists of 11 deck span section and three major arches with four main piers and two additional sets of supports at the western end.

• 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.

The main bridge arch structure rises to a height of 60 m above water level with the road crowning to a height of 20 meters above mean water level.

• 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 central pier alone contains enough concrete to cover a football pitch to a height of five meters. • The steel arch cross-sections are up to 6 x 8 meters• Construction of a 800m long bridge linking Abu Dhabi with the mainland has a central span of 234m.• The main bridge is a hybrid structure, consisting of central steel asymmetric arch ribs supporting pre-

stressed concrete box girder decks. • At the two main channel piers, the decks are supported by inclined pre-stressed concrete supports, rising vertically from the pier pile caps.• The steel arch segments were designed with end-bolted connections, using 75mm Macalloy bars.

• The main support structure is continuous through the bridge, making the locked-in forces from the sequence of construction an important consideration.

• Seismic Isolation System was incorporated to reduce the forces required to connect the deck to the support structure
