An attempt to take advantage of a U.S. Department of Transportation program designed to help socially disadvantaged small businesses has resulted in a $2.4 million settlement between a Plainville-based construction company and the federal government.

According to the U.S. Attorney’s Office in Connecticut, Manafort Brothers Inc. submitted a bid to the Connecticut Department of Transportation in 2007 to serve as general contractor on a project funded both federally and by the state that involved a two-mile relocation of Route 72 in Bristol and Plainville. The project also included a 2.4-mile reconstruction of existing secondary roads.
