On the surface, the span looks like any of the thousands of small, narrow two-lane bridges across America. This new, high-tech bridge in Morgan County, Tennessee uses G/flex® Epoxy in a fiber-reinforced polymer (FRP) composite material deck embedded with fiber optic sensors. It replaced a damaged, decades-old concrete crossing which, like thousands of low-volume bridges across the nation, was structurally deficient and outdated.
