Michigan State professor to put sensors on Mackinac Bridge

By  | 

EAST LANSING (AP) - (09/04/16) - 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 (http://on.lsj.com/2c6ctBq) 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.
