As if Dubai was missing landmarks, it is planning to build... the tallest and largest arch bridge in the world. Dubai likes it bigger, taller, and more expensive than anyone else. It was just a matter of time before they decided to build this. The bridge will bet 670 feet tall and will have 12 lanes of traffic. This means it will be able to carry up to 2,000 vehicles per hour. It should be finished for 2012 and it will cost about $817 million.
