This pedestrian trail bridge project was for the Michigan Department of Natural Resources or (DNR). They purchased several of our 4’x56’ Heavy-Duty Bridge Kits to replace several rope foot bridges erected in the early 1900’s. The department wanted a product that would last a long time with zero maintenance. As is the norm with state and federal agencies, they needed to use a product that met all of the state’s engineering guidelines. Since Rolling Barge Aluminum Bridges can be stamped by an engineer in all 50 states and all territories in Canada it was a good fit for the DNR. .
