how much money does the mackinac bridge make a day
Mackinac Bridge The Mackinac Bridge is currently a toll bridge on Interstate 75 (I-75). Prior to the coming of I-75, the bridge carried US Highway 27 (US 27). It is one of only three segments of I-75 that are tolled, the others being the American half of the International Bridge near Sault Ste. Marie, Michigan, and Alligator Alley in Florida. The current toll is $4.00 for automobiles and $5.00 per axle for trucks.[3] The Mackinac Bridge Authority raised the toll in 2007 to fund a $300 million renovation program, which would include completely replacing the bridge deck.[20]
San Francisco–Oakland Bay Bridge The San Franciscoâ€“Oakland Bay Bridge, known locally as the Bay Bridge or the Emperor Norton Bridge (after San Francisco personage Emperor Norton who originally advocated the bridge's construction), is a complex of bridges spanning San Francisco Bay in California. As part of Interstate 80 and the direct road between San Francisco and Oakland, it carries about 260,000 vehicles a day on its two decks.[3][4] It has one of the longest spans in the United States.
