These new roadways were built during a twelve-year period from 1994 to early 2006. The massive project became the largest urban construction project ever undertaken in American history. Construction on the new I-93 segment was not without serious issues: a lengthly Federal environmental review pushed the start of construction back from approximately 1990, causing many inflationary increases; funding for the project was the subject of several political battles between Pres.

when a 25 foot section of bridge deck on the northbound side partially collapsed due to age-related structural fatigue. 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. MassDOT set in motion a plan to replace the superstructure and concrete decks on 14 overpass bridges along that section of the interstate. 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. Traffic was diverted into a series of crossover lanes during construction. The main part of the project took place each weekend from June through August 2011,with the exception of the July 4th holiday weekend. One or two bridges were replaced each weekend during the construction time frame. The project was part of the Commonwealth's Accelerated Bridge Program.

, New Hampshire is set to receive several million dollars in highway construction funds. One of the projects will be widening a portion of the highway between the Massachusetts border and Manchester. Bidding is set to begin in February 2009 with construction slated to begin in late 2009 or early 2010. The plans call for the New Hampshire Department of Transportation to widen the southernmost 20 miles (32.2 km) of I-93 to four lanes in each direction, from the current two. In addition, all five interchanges along this length will be upgraded to accommodate larger amounts of traffic, including replacing many aging bridges. Smaller construction projects at some of the interchanges are already taking place. According to plans filed by the state with US DOT, the project is scheduled to run from 2009 through 2016, with work starting at the Massachusetts line and moving northward to Manchester. The project is designed with an intermodal transit bent; new or improved park and ride facilities deployed at exits 1, 3 and 5 and a widened median strip that is designed to accommodate a planned commuter rail service between Boston and Manchester.
As a way to help defray the costs of the expansion, in early 2010 the NHDOT made a formal request to the

The proposal faced opposition from state legislators in both states who claimed the tolls would cause severe congestion in the area and lead to an economic burden to local residents.

The new policy was laid out by Transportation Commissioner George Campbell after reviewing the proposal and receiving a promise from the MassDOT that it would not be enacting a similar toll on the Massachusetts side of the border.
