1. Mackinac Bridge, Michigan Marker
Inscription. Designed by David B. Steinman, and representing a new level of aerodynamic stability in suspension bridges for its time, the Mackinac Bridge was the first suspension bridge to incorporate specific design features to manage the forces imposed on it by winds, construction of "Mighty Mac" took over three years in a demanding climate, and its completion made all-weather travel between Michigan's two regions possible. The five-mile bridge, including approaches, was the world's longest suspension bridge between cable anchorages (8,614 feet) at the time of its construction.

Opened to Traffic: November 1, 1957
 
Erected 2010 by American Society of Civil Engineers.
