Harbor Technologies built this bridge in Boothbay, which is currently the largest composite bridge in the world. The company says it's also built the world's largest vehicular composite-bridge beam, which it will send to Missouri.

Harbor Technologies LLC of Brunswick says the 105 foot, 7 inch beam is the world's largest vehicular composite bridge beam. It's 6 feet wide and 5 inches deep.

The so-called hybrid composite beam will be part of a Missouri Transportation Department project which is repairing and replacing 802 bridges over five years. The Maine-made beam is one of three Harbor Technologies is providing for the project.

The contractor for the bridge work says the Fiberglass-coated composite beams, which also are made of Styrofoam and some steel and concrete, have advantages over standard steel or concrete beam forms. They're much lighter, just as strong and are corrosion resistant.
