The FRONTLINE Dispatch presents The Big Dig, Part 1: “We Were Wrong.”

The Big Dig is a new 9-part podcast series from GBH News, hosted by Ian Coss.

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 Boston’s Big Dig. Infamous for its ever-increasing price tag, this massive highway tunneling effort became a symbol of waste and corruption. Yet the project delivered on its promise to transform the city. So how did the narrative go so horribly wrong? And what lessons can the Big Dig offer for the ambitious projects of today?

You can listen all nine episodes of The Big Dig at GBH News, or wherever you get your podcasts.
