The Medway Highway Bridge is a Fiber-Reinforced-Polymer (FRP)-glulam girder bridge with a glulam deck. It was designed by University of Maine and Maine Department of Transportation (DOT) engineers. A monitoring program is evaluating in particular the integrity of the FRP and the FRP-wood bond line. The two lane bridge consists of 15 horizontally laminated GFRP/glulam beams.
