Hybrid Composite Beams

As part of its Safe & Sound Bridge Improvement Program, MoDOT received a $1 million federal “Highways for Life“ grant to utilize hybrid composite beams on three bridge projects -- in Douglas, Shannon and Dade Counties. These innovative structural elements are much lighter than conventional steel or concrete beams which make them easier to transport and install. The exterior of HCBs is fiberglass which makes them more resistent to water and chlorides and thus, longer lasting.
