United States - Mackinac Bridge


Stamp Issue : 1958-06-25 

Mackinac Bridge is a suspension bridge spanning the Straits of Mackinac to connect the non-contiguous Upper and Lower peninsulas of the U.S. state of Michigan. Envisioned since the 1880s, the bridge was completed only after many decades of struggles to begin construction. The bridge connects the city of St. Ignace on the north end with the village of Mackinaw City on the south. It is the longest suspension bridge between anchorages in the Western hemisphere.
The bridge opened on November 1, 1957, ending decades of the two peninsulas being solely linked by ferries. A year later, the bridge was formally dedicated as "the world's longest suspension bridge between anchorages". At 2,626 m, the Mackinac Bridge is the longest suspension bridge with two towers between anchorages in the Western Hemisphere. The length of the bridge's main span is 1,158 m, which makes it the third-longest suspension span in the United States and twelfth longest worldwide.
