I happen to share a birthday with the Mackinac Bridge. On November 1, 1957, the day I turned five, the bridge was opened to the public for the first time. Since this month is the 50th anniversary of that event, there has been a great deal of publicity about this magnificent structure. Even though I was very young at the time, I can still remember crossing the Straits of Mackinac on the car ferry with my parents and our 1951 Plymouth. Later on, it was really a thrill to be able to travel on the bridge, which is not only wonderfully effective in function but also strikingly beautiful in form. Our library has many books, periodicals, and file materials about the bridge, from the years of the planning process all the way down to the present day. One recent publication I found particularly interesting is
NORTHERN MICHIGAN ALMANAC by Ron Jolly (2005), which is shelved with the
Local History collection. It has several pages of fascinating facts such as:
Workers employed at the construction site: 3500
Number of steel rivets: 4,851,700
Number of steel bolts: 1,016,600
Height of roadway above the water: 199 ft.
Total length of wire in cables: 42,000 miles
Number of wires in each cable: 12,580
Weight of cables: 11,480 tons
Total weight of bridge: 1,024,500 tons
First snowmobile crossing: February 14, 1970
First birth on bridge: May 11, 1983 [see p. 384 for the story!]
First Amish buggy to cross: June 30, 1973
First bridge walk: September 7, 1959
Highest wind gust recorded: 128 mph on May 9, 2003
Most crossings in a year: 4,936,417 in 1999
Most crossings in a day: 37,846 on June 29, 1996 [see p. 386 for why!]
50 millionth crossing: September 25, 1984
100 millionth crossing: June 25, 1998
This is only a small representation of the vast amount of detail Jolly presents about the northern region. In these days when much of the news about our state is not so good, it’s reassuring to reflect on the great achievements of our citizens as well as the natural beauty of Michigan.
