The Straits of Mackinac Shipwreck Preserve are divided in two by a bridge spanning how long?
Mackinac Bridge 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 26372 ft bridge (familiarly known as "Big Mac" and "Mighty Mac") is the world's 19th-longest main span and the longest suspension bridge between anchorages in the Western Hemisphere. The Mackinac Bridge is part of Interstate 75 and the Lakes Michigan and Huron components of the Great Lakes Circle Tours across the straits; it is also a segment of the U.S. North Country National Scenic Trail. The bridge connects the city of St. Ignace on the north end with the village of Mackinaw City on the south.
Daniel Carter Beard Bridge The Daniel Carter Beard Bridge (also known colloquially as the Big Mac Bridge), is a yellow twin span steel tied arch bridge crossing the Ohio River in Cincinnati, Ohio. It carries Interstate 471 between Cincinnati, Ohio, and Newport, Kentucky. As to the origin of this nickname, its yellow arches are said to be similar to the "Golden Arches" logo of McDonald's restaurant. The nickname was coined by local residents after the bridge's golden arches were constructed. In the 1980s, McDonald's considered opening a floating restaurant at the base after the nickname caught on, but never went to construction. This bridge has a main span of 750 feet and has a total span of 2100 feet. It is named in honor of Daniel Carter Beard, the founder of the Sons of Daniel Boone and one of the founders of the Boy Scouts of America.
