Polymer grid technology a boon for bridges

When the long-awaited Highway 151 bypass around Fond du Lac, Wisconsin, opens later this year, vehicles traveling northbound will cross DeNeveu Creek on a bridge like no other in the country.
Externally, the bridge looks identical to its adjacent twin. However, internally, the concrete deck reinforced with a novel fiber-reinforced polymer (FRP) grid system that could replace conventional epoxy-coated reinforcing bars (rebars) inside future bridges.
