6. Mackinac Bridge
Stretching an impressive five miles, the Mackinac Bridge stands as one of the world’s longest suspension bridges. Completed in 1957, it boldly links Michigan’s Upper and Lower Peninsulas, overcoming the formidable Straits of Mackinac. This engineering marvel is a monument to mid-century American ambition, transforming regional travel and commerce. The bridge’s graceful lines and sheer scale have made it an enduring symbol of Michigan pride.
