Brunswick, ME – Structural Monitoring Solutions (SMS) has been awarded a contract by the Maine Department of Transportation (MaineDOT) to implement long-term structural health monitoring for the Deer Isle Bridge, an 85-year-old suspension bridge connecting Deer Isle to the mainland across Eggemoggin Reach.​The Deer Isle Bridge is one of Maine’s most recognized engineering landmarks. Its helical wire suspension cables are rare among U.S. bridges, and MaineDOT is taking a proactive approach to monitoring their condition as the structure continues to age.​SMS will deploy a system that integrates acoustic sensing and fiber optic strain monitoring, providing continuous data on cable performance, wire break events, and overall structural behavior. This real-time insight allows for early detection of potential issues and supports informed maintenance planning.

​

“It’s a privilege to support MaineDOT in protecting this historic bridge,” said Terry Tamutus of SMS. “Our technologies are designed to enhance safety, reduce long-term costs, and extend structural life.”

​

This project builds on SMS’s work with other major bridges in Florida, New York, and California.
