Mackinac Bridge. Taken from the ferry from Mackinaw City to Mackinac Island. Don't ask me to explain the Mackinaw / Mackinanc thing, I have no idea...
The Mackinac Bridge is a suspension bridge spanning the Straits of Mackinac to connect the Upper and Lower Peninsulas of the U.S. state of Michigan. Opened in 1957, the 26,372-foot-long bridge is the world's 24th-longest main span and the longest suspension bridge between anchorages in the Western Hemisphere" - Wikipedia
