EAST LANSING, Mich. (AP) — A Michigan State University engineering professor plans to install sensors on the Mackinac Bridge to monitor stress on the aging structure.

Professor Nizar Lajnef tells the Lansing State Journal the stress sensors that will be placed on the bridge later this month are a test of a project he’s been working on for seven years with funding from the Federal Highway Administration.

A recent grant of $1.5 million to MSU, Washington University at St. Louis and the University of Nevada-Reno will put sensor prototypes in place at several spots around the country. He says if it works, the stress sensors could become commonplace on structures around the country.

The 5-mile-long Mackinac Bridge that connects Michigan’s two peninsulas is the third-longest suspension bridge in the world.
