Jim Vrabel, the author of the new book, A People's History of the New Boston, will lead a discussion of the campaign that stopped construction of the proposed Southwest Expressway (I-95) through Jamacia Plain and the rest of Boston in the 1970s. Current and former J.P. residents featured in the book's "People Before Highways" chapter will discuss those tumultuous days and and describe how residents were able to stop the highway from being built and persuade the state and federal government to support construction instead of today's Orange Line and Southwest Corridor Park instead. Input from anyone involved in the campaign will also be welcomed. Free and open to the public. Refreshments will be served, cash bar, books on sale.
