 The collapse forced the Massachusetts Department of Transportation to evaluate the remaining bridges along the corridor, eventually deciding to replace several bridges along the highway in a plan called 93 Fast 14.The MassDOT set in motion a plan to replace the superstructure and concrete decks on 14 overpass bridges along that section of the interstate, using rapid bridge replacement methods.The $98.1 million project replaced bridges originally built in 1957 with a set of prefabricated modular concrete bridges in a series of weekend roadway closures.
