Notice: After 22 years and over 900 weddings I am retiring from the wedding industry.

Another chapter with magical, music memories from beautiful Mackinac Island, MI. To all my family and friends, I miss you all so much. PL&H.

Mackinac Bridge.

Mackinac Bridge 2005

I have driven across the Mackinac Bridge 100’s of times and walked it once.

Once a year the Bridge is open for the Labor Day Walk.

The Mackinac Bridge is currently the third longest suspension bridge in the world. In 1998, the Akashi Kaikyo Bridge in Japan became the longest with a total suspension of 12,826 feet. The Great Belt Bridge in Halsskov-Sprogoe, Denmark, which also opened in 1998, is the second longest suspension bridge in the world with a total suspension of 8,921 feet. The Mackinac Bridge is the longest suspension bridge in the western hemisphere.

All suspension bridges are designed to move to accommodate wind, change in temperature, and weight. It is possible that the deck at center span could move as much as 35 feet (east or west) due to high winds. This would only happen under severe wind conditions. The deck would not swing or “sway” but rather move slowly in one direction based on the force and direction of the wind. After the wind subsides, the weight of the vehicles crossing would slowly move it back into center position.
