design a bridge structure across the bering

What a great contest I read about over at BldgBlog! Design a bridge across the Bering Strait, connecting the U.S. to Russia, and you could win as much as $80,000 ($20,000, if you're a student).

From the competition website:
This project is a dream project attempting to connect two continents. In a wide sense, it includes building a tunnel or a bridge at both ends of the strait, extending [the] existing railways of the United States and Russia, and laying a world highway around the coasts of the world, which require a massive amount of construction.
Your only two requirements are to design "a peace park with a bridging structure using the two islands, Big Diomede and Little Diomede at the Bering Strait," and a "proposal of how to connect two continents."
