The Mackinac bridge (which connects the lower and upper peninsulas of Michigan) is the 3rd largest suspension bridge in the world. At five miles in length, it is the third-longest suspension bridge in the world. Seriously, check it out… it’s pretty big. There’s actually a traffic jam on there too. Thanks to Ryan, Soyle Mycelf, Otterpop and Parker. More info about the bridge is available at mackinacbridge.org.
