Algonquian peoples originally called the region Michilimackinac, meaning Place of the Great Turtle.[1] In 1884, a St. Ignace store owner published an advertisement captioned "Proposed bridge across the Straits of Mackinac"[2] The Mackinac Straits Bridge Authority was abolished in 1947, but a new Mackinac Bridge Authority was created in 1950.[2][3] Construction began on May 7, 1954, and the bridge opened to traffic on November 1, 1957.[2]
Between 1934 and 1936, the Authority applied twice for loans and grants from the Federal Emergency Administration of Public Works, but both requests were turned down.[2] In January 1953, Steinman was appointed as the design engineer for the Mackinac Bridge.[4]
What the cited sources add
The American Society of Civil Engineers notes the Mackinac Bridge was the first long-span suspension bridge to incorporate a porous deck for aerodynamic stability.[4] The Mackinac Bridge Authority states the bridge is currently the seventh-longest suspension bridge in the world by total suspended length.[5] The Authority also reports the last Mackinac Bridge bonds were retired on July 1, 1986.[2] One year after the bridge opened, the five-mile structure (including approaches) was formally dedicated as the world's longest suspension bridge between cable anchorages.[4]
