MassDOT began the demolition of all existing toll plazas in October 2016 as part of the implementation of All Electronic Tolling along the Mass Turnpike. Brennan Consulting has been on site since Sept 2016, performing verification and expansion of existing control for all plazas, layout of all utilities and structures, mark out of limit of work and slit fence, and the development and submission of numerous as built surveys. Work is ongoing.
