AlumaBridge brings lighter, sustainable solution to bridge repair

When a bridge collapses, hand-wringing and fear become the rule of the day. And yet attention to infrastructure never seems to be a priority until it’s too late. A new Ann Arbor-based startup is working to get ahead of that problem before the worst happens.

AlumaBridge uses aluminum as its principal material for prefabricated pieces of bridging in order to extend the life of aging bridges. The aluminum bridge deck panels are made using friction stir welding and have a non-skid surface. They can easily be applied to the steel girders on existing bridges, giving many more years of service.

"I would like to address some of the nation's most deficient structures,” says Greg Osberg, president & CEO of AlumaBridge. "It's a matter of getting the technology out there and commercializing it."

Osberg worked at Sopa Extrusions studying new ways to extend the life of the countries aging infrastructure. His work focused on aluminum bridge options and he spun out AlumaBridge last fall. The company is now working to install its first bridge in Quebec and is working on test panels for bridges in Florida. Check out a video describing AlumaBridge’s product and installation here.

"It mirrors the strength of concrete but is one fifth of the weight," Osberg says.

Stories of the country’s aging bridges have grown more numerous in recent years. Last year "an Associated Press analysis of 607,380 bridges in the most recent federal National Bridge Inventory showed that 65,605 were classified as "structurally deficient" and 20,808 as "fracture critical." Of those, 7,795 were both — a combination of red flags that experts say indicate significant disrepair and similar risk of collapse," according to a story in USA Today.

"This (AlumaBridge’s product) offers them an option," Osberg says. "It offers them a longer bridge life with a recyclable product."
