A New York architectural firm has been selected by Dubai authorities to design the longest and what could be the most expensive arch bridge in the world.
The firm FXFOWLE has designed a unique structure that will include massive archways that will tower 205 metres above 12 lanes of traffic and two railway lines carrying Dubai Metro trains along the Green Line.
The bridges largest main span will be 667 metres long, eclipsing the 550-metre main span of Lupu Bridge in Shanghai, China, which is currently the worlds longest arch bridge.
The Dh3-billion project will take four years to build, said Mattar Al Tayer, Chairman of the Roads and Transport Authority.
It should be completed by the end of 2012 if not sooner, he told XPRESS following a press conference Tuesday.
Images of the proposed structure reveal an ambitious plan to erect a sixth crossing over Dubai Creek that will link Dubai Festival City and Al Jaddaf on the west side of the creek.
The design is based on an acoustic wave and will depend on an artificial island built just to the north of the existing Creek Island where the proposed Dubai Opera house is planned in coming years.
Al Tayer told reporters that the project is one of the largest in the RTAs history and is so large, in fact, that it will require the project to be done in six phases. Construction will take four years to complete.
The proposed bridge will be located south of the existing Business Bay Crossing and will be large enough to handle 20,000 vehicles per hour across 12 lanes in total, six lanes in each direction, Al Tayer said.
The metro train will carry 23,000 passengers an hour across the bridge.
The bridge will rise 15 metres above the creek to allow for free navigation, although the floating bridge to the north which was erected last year has already blocked some boats.
Despite the bridges scale, the RTAs Traffic and Roads Agency CEO Maitha bin Adai said that the structure has been designed to be integrated into the environment and natural surroundings.
She said that is the beauty of the design, the harmony of construction that fits into the environment.
The firm FXFOWLEs international director Steven Miller couldnt be reached for comment at the companys Dubai office on Tuesday.
But the company states on its website that it is committed to creating architect6ure which stimulates and inspires; an architecture that tells the story of place, of institutional and individual aspiration, and of synergy between the natural and built realms.
Over the years, the meaning of green architecture and sustainable design has evolved an FXFOWLE has remained in the forefront of that dialogue, the firm stated.
Images released by the RTA show that the bridge will be illuminated at night in a way that resembles the varying fullness of the moon.
FAST FACTS
The bridge will cost Dh3 billion Construction will take four years The giant arch is 205 metres high and 667 metres long making it the longest span in the world The Green Line of the Dubai Metro will pass down the centre of the new bridge The project will serve Dubai Healthcare City, Sama Al-Jadaf and Culture Village There will be 12 lanes on the bridge, six in each direction The bridge will be 15 metres above the creek surface to allow for free navigation

$100 a barrel of oil buys plenty of toys (not to mention bombs, madrassahs, and board seats in US companies)
That’s not an arch bridge. It’s a suspension bridge.
Not Guilty!
If the current 'Disneylandia' (to use a non-word) over Dubai ends, the city will end up being one of the world's prettiest failures.
It's suspended from an arch not a cable.
Looks like Crusty-The-Pantsuit...only worn a bit high-waisted.
The bridge still depends on the arch for support (as opposed to towers in ordinary suspension bridges).
You mean natural gas.
Dubai doesn’t have so much oil. They’ve made their money mostly on commerce. Abu Dhabi possesses most of UAE’s oil (more than 90%). Which means that after the oil runs out, Dubai’s wealth will last, while Saudi Arabia’s will decline.
The upper bridge is what an arch bridge looks like. Its the one over the New River in WVA. Its the longest one in the Western Hemisphere.
I know the bridge from Saudi to Bahrain is huge .... beautiful too.
That is a LOT of steel.
Wow. Where’s the environmental impact statements for the, carbon footprint, snail darter, spotted owls and all the other must haves before projects like this can be started?
I suppose you have to spend billions of oil dollars on something but why not spend it on making your country marginally habitable? (greening the desert like Israel) as opposed to builidng bridges and shopping malls with skiing hills in them.
I noticed that the Chinese version also used suspension. That’s not a pure arch bridge. I guess I’m a purist.
At $85 a barrel for oil, UAE annual production of oil is worth more than 8 times as much as their annual production of natural gas.

Nice link. Thank you.
