Fifteen stunning bridges and 3 proposed

Fifteen great bridges, one about to begin construction, one proposed. One is a distant pipe dream - across the Bering Straight. It is 50 miles across treacherous seas. There are two islands in the right place - the Diomedes - that could help. But it's 66 degrees north, just below the Arctic Circle. And, still, what would it connect? A very distant peninsula in Siberia to a very remote peninsula 120 miles from Nome, Alaska, which is not close to anything! But enjoy the others. They are great. Google Earth has beautiful 3-D models of the Golden Gate (8th longest single span), Bosporous bridge in Istanbul, Turkey (14th) and Oakland Bay bridge. Frikoo
