UAE's first cable-stayed bridge nears completion
A major pedestrian bridge across Dubai's busy Sheikh Zayed Road is set to be completed this month. The US$1.8 million structure is the first cable-stayed bridge in the United Arab Emirates. The bridge has a 52m-high central pylon, 16 wire ropes and a slender deck with free spans of more than 65m, allowing it to cross 10 lanes and slip roads as well as an underpass. Its girder is of composite design with steel main girders and a hollow concrete deck to provide the necessary torsional and transverse stiffness. Dubai Municipality's roads department is building this and four other bridges under a design and build contract. Head of roads construction Badr Al Gergawi said that a more conventional design would have required a massive bridge girder, spoiling the view of the skyline.
