The winning bidder in the controversial procurement for 18 Mass Pike highway service plazas is walking away from lease talks with the state. “After three months of good faith negotiations, Applegreen and MassDOT have not reached agreement on definitive terms for the redevelopment of 18 motorway service areas in Massachusetts,” Applegreen said in a statement released late Tuesday.
