There is a cynicism that hangs over the topic of American infrastructure – whether it’s high-speed rail or off-shore wind – it feels like this country can’t build big things anymore. No one project embodies that cynicism quite like what Bostonians call ‘The Big Dig.’ Infamous for its ever-increasing price tag, this massive highway tunneling effort was once ridiculed as the Big Mess, the Big Hole, the Big Pig, the Big Lie. But now, decades later the story looks more complicated. So how did the narrative around this project go so horribly wrong? And what lessons can it offer for the ambitious projects of today? The nine episode series is produced by GBH News and hosted by Ian Coss. Producers are Ian Coss and Isabel Hibbard. Editor is Lacy Roberts. Executive Producer is Devin Maverick Robins. Editorial Advisor is Stephanie Leydon with fact checking by Lisa Wardle. The Project Manager is Meiqian He.
