Mackinac Bridge Dedicated as ASCE Historical Civil Engineering Landmark
Past President of the ASCE Michigan Section and HRC Associate Tom Maxwell, P.E., was joined by ASCE National President, Kathy Caldwell, P.E., and the Director of the Michigan Department of Transportation, Kirk Steudle, P.E., at a dedication ceremony to designate the Mackinac Bridge as an ASCE Historic Civil Engineering Landmark. The event was featured in the October 2010 issue of the nationally distributed ASCE magazine as well as a YouTube video (www.youtube.com/watch?v=C3XkS2z3cRg). The attendees were joined by the chairman of the Mackinac Bridge Authority Bill Gnodtke and the executive secretary Robert Sweeny. The bridge between the upper and lower peninsulas of Michigan was opened to traffic in 1957 and currently carries well over 3.5 million cars per year. Known as the “Mighty Mac” to Michiganders, it crosses the Straits of Mackinac between Lakes Huron and Michigan and is one of the longest suspension bridges in the world. The design of the bridge was influenced by research following the 1940 catastrophic failure of the Tacoma Narrows Bridge in Washington State. After the ceremony, Tom Maxwell and others enjoyed a trip to the top of the main tower, 552 feet (168 meters) above the straits. Some pictures of their adventure are shown below.
