is the clark memorial bridge a toll bridge
George Rogers Clark Memorial Bridge It was designed by Ralph Modjeski and Frank Masters with architectural details handled by Paul Philippe Cret of Philadelphia, and construction began in June 1928 by the American Bridge Company of Pittsburgh at a cost of $4.7 million. President Herbert Hoover dedicated the bridge.[2] It was opened to the public on October 31, 1929 as the Louisville Municipal Bridge and operated as a toll bridge. The toll was 35 cents until December 31, 1936, when it became a quarter. The last of the bonds that financed the construction were redeemed in 1946, and the tolls were removed.[3]
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]
