It was a big day for the Mackinac Bridge.
The American Society of Civil Engineers is calling the Mackinac Bridge a National Historic Civil Engineering Landmark.
Since 1964, the organization has recognized around 200 projects world-wide.
The organization picks structures that are unique, innovative and creative.
The Mackinac Bridge was the longest suspension bridge in the world when it was built and represented a new level of aerodynamic stability.
9&10's Christina Vecchioni and photojournalist Aaron Smith have more details from the ceremony.
