In October 2016, MassDOT become a cashless toll state with its conversion to All Electronic Tolling in order to improve safety, reduce congestion, and improve air quality. The $130 million project involved converting from 26 tollbooth locations to 16 overhead gantries, which enable drivers to travel at highway speeds and not slow down to pay their toll. The conversion to All Electronic Tolling meant that the legacy toll plazas could be demolished, and the roadway reconstructed to facilitate travel at normal highway speeds. The project is already producing results—travel time has been substantially reduced for drivers around the state.
