A portion of the Mackinac Bridge, which connects Michigan’s upper and lower peninsulas where Lake Huron meets Lake Michigan. This photo represents part of the human experience of steel as its larger than life structure crosses two adjoining bodies of water that, of themselves, are also massive on a seemingly unattainable scale. The person standing at the edge of the water looking out at the bridge provides a visual scale for a comparison of how we, as humans, use steel to achieve greatness beyond ourselves. Photo and description by Krystal Brun.
The winning photo in the 2011 AISC Student Photo Contest was taken by Krystal Brun, a senior civil engineering student at George Washington University, Washington, D.C. Brun captured this sunset at the south end of the Mackinac Bridge over the Memorial Day weekend in 2010, the night before joining the other 596 runners in the 7th annual Mackinaw Memorial Bridge Race on May 29.
The third longest suspension bridge in the world, the 5-mile-long Mackinac Bridge officially opened on November 1, 1957, and has played host to pedestrian events since the beginning. This year September 5 marked the 54th annual Mackinac Bridge Walk. The event is held each year over the Labor Day weekend and attracts thousands of participants.
The Memorial Day Bridge Race over the Mackinac Bridge was initiated in 2004, and 2009 saw the launch of the Fall Colors Bridge Race. (Also in 2009, ASCE named the bridge a National Historic Civil Engineering Landmark.) Organized by the Mackinaw Area Visitors Bureau, Mackinaw City, Mich., both races have become annual events despite the fact that runners face a steady incline with a slope of 5 degrees for the first half of the 5.6-mile course.
The 3rd Annual Fall Colors Bridge Race is scheduled for Saturday, October 8. Unlike the Memorial Bridge Race, which goes from south to north, the Fall Colors Race begins at the north end of the bridge. Click here for registration information. The Mackinac Bridge webcams should offer a glimpse of the race, which begins at 7:30 a.m. Eastern time.
