The bridge opened on November 1, 1957, [10] connecting two peninsulas linked for decades by ferries. At the time, the bridge was formally dedicated as the "world's longest suspension bridge between anchorages", allowing a superlative comparison to the Golden Gate Bridge, which has a longer center span between towers, and the San Francisco–Oakland Bay Bridge, which has an anchorage in the middle.
By the mid-1930s Steinman had a professional reputation as one of the pre-eminent bridge engineers of the US, especially for long span suspension bridges, but his bridges were eclipsed in the public eye by his old rival Ammann's George Washington Bridge (1931) and by Joseph Strauss's Golden Gate Bridge (1937) among others. His plans for a NYC ...
During the construction of the Mackinac Bridge from 1954 to 1957, the Mackinaw would clear away ice floes piling up against the massive caissons surrounding the bridge piers being constructed. This allowed the foundations of the bridge to settle into place undisturbed during the winter.
A two-month repaving project on the Mackinac Bridge is expected to reduce traffic to one lane in each direction and lead to traffic backups and delays, especially during the weekends, the Mackinac ...
The Tacoma Narrows Bridge had a width-to-span ratio of 1 to 72, while the proposed Mackinac design had an even more extreme width-to-span ratio of 1 to 92. [8] It wasn't until Steinman took into account what was learned at Tacoma and brought on Woodruff as a design engineer that the Mackinac Bridge was finally built starting in 1954.
The Mackinac Bridge was completed in November 1957. During its construction, crowds came to watch the progress, increasing the need for tour boats. During the winter of 1953, Shepler built a second kit boat, a high-speed cruiser, the Billy Dick, named after the captain's son, William Richard. The fleet expanded over the years.

It continued until the day the Mackinac Bridge opened. The law required the ferry service to cease so that the bridge would not have competition and could pay off its construction bonds faster. The passenger ferries and many of the rail ferries across the Detroit and St. Clair rivers had ended after the bridges and tunnels were built.
