Sweet vindication

The largest contractor on the Big Dig pleaded guilty yesterday to 39 federal charges of overbilling and lying about construction defects on the project, but prosecutors dropped five other charges that had implicated the company in the fatal 2006 collapse of the ceiling of the Interstate 90 tunnel.

The Cambridge company, Modern Continental Corp., hailed as vindication the decision by the US attorney's office to drop the five charges resulting from the accident that killed a car passenger, Milena Del Valle.
