Hybrid Composite Beam

This is an image of a hybrid composite beam used in bridge construction.

The Hybrid Composite Beam (HC Beam) was developed by John Hillman and is being manufactured by Harbor Technologies, a Maine composites company. Two highway bridges, using this innovative beam of composite shell, concrete arch and tension reinforcement, have already been constructed: one in Illinois and the other in New Jersey. MaineDOT has embraced this technology and is using HC Beams in the construction of the Knickerbocker Bridge in Boothbay. A total of 4300 linear feet of the HC Beams will be installed with a traditional reinforced concrete deck. This is the first multi-span continuous beam using this technology.
