The world's largest arch bridge

This will be the world's largest arch bridge, with 2000 vehicles set to cross its 12 lanes—per hour, in each direction.

Dubai's Mile-Long Super Bridge construction is set for March for completion in 2012.

At 670 ft. tall, Dubai's next super structure will stand higher than the George Washington Bridge (604 ft.) but fall short of San Francisco's existing Golden Gate Bridge (746 ft.).
