World's Tallest Arch Bridge
They do things differently in Dubai. They like their stuff bigger, taller, and more expensive than anywhere else. So it only makes sense that construction of the world's tallest arch bridge begins next month. The bridge will peak at 670 feet, have 12 lanes of traffic, and handle up to 2,000 vehicles per hour. Scheduled completion is slated for 2012, after $817 million in construction.
