Harbor Technologies LLC (Brunswick, Maine, USA) reported on Feb. 8 that it has manufactured the world’s largest vehicular composite bridge beam. At 105.6 ft long, 6 ft wide, and 5 ft deep (32 by 1.8 by 1.5m), the HCB (hybrid composite beam), for the State of Missouri Department of Transportation (DOT), is said the world’s longest vehicular composite bridge beam.

Harbor Technologies made the bridge for the Missouri Department of Transportation’s Safe and Sound bridge replacement project. The Safe and Sound program, which started in 2009, is underway repairing and replacing 802 bridges in five years. Some 672 bridges have already been completed to date. This particular beam is for one of three bridge jobs that Harbor Technologies is supplying HCB’s to the Safe and Sound project.

A total of three HCBs are being supplied for the single-span bridge replacement over Sons Creek on highway 97 in Dade County, Mo. The contractor for the job is KTU Constructors, a joint venture between Kiewit Western, Taylor Brothers and United Contractors.

Harbor Technologies has been manufacturing HCBs, invented by John Hillman, since the first prototype beam was tested early in 2009. Since then, bridge beams of various sizes have been installed in Texas, New Jersey, Maine and Illinois.
