New Composite Bridge in Tennessee Showcases Sustainable Solution for Aging Infrastructure IACMI: Due to the use of technologically advanced composites, the bridge deck system requires less installation time, reduces energy and construction costs, and has a 100-year lifespan News provided by Share this article Share this article KNOXVILLE, Tenn., April 7, 2021 /PRNewswire/  On the surface, it looks like any of the thousands of small, narrow two-lane bridges across America. But a new, high-tech bridge in north central Tennessee is equipped with a fiber-reinforced polymer (FRP) composite material bridge deck embedded with fiber optic sensors. It replaced a damaged, decades-old concrete crossing which, like thousands of rural, low-volume bridges across the state and nation, was rated structurally deficient and outdated.
