Demolition work on the Massachusetts Turnpike’s 23 toll booths began two days after All Electronic Tolling was activated on Oct. 28. Gantries along the turnpike, Tobin Bridge and Boston tunnels read E-Z Pass transponders and photograph license plates before automatically billing drivers without transponders. The first phase of the $132.82-million project involving six contractors includes demolishing the middle toll booths while traffic is diverted around the work. Workers will knock down the booths and fill in the tunnels connecting the booths before paving the highway. MassDOT says this first phase of the project will be completed by Nov. 22, at which point the second phase to remove the outer toll booths will begin.
