The U.S. Postal Service honors the Mackinac Bridge in Michigan as the subject of its 2010 Priority Mail stamp. The bridge, nicknamed "Mighty Mac," connects the two peninsulas of Michigan.
The longest suspension bridge in the Western Hemisphere, the Mackinac extends from Mackinaw City at the south end to St. Ignace on the north side. Opened in 1957, the Mackinac Bridge Cost nearly 100 million dollars and took over three years to complete. The sturdy five-mile bridge is designed to support 38,486 tons and can move up to 35 feet in high winds.
Artist Dan Cosgrove used several panoramic photographs of the Mackinac Bridge to create the stamp arwork, which features seagulls flying around the two towers and a large ship passing underneath. This is one of several designs that the artist has produced for the U.S. Postal Service
