Boston's Big Dig started as a vision for a large-scale highway tunnel system that became a cautionary tale about American infrastructure. Guest host Nancy Solomon speaks with Ian Coss, host of The Big Dig podcast from WGBH and PRX, which dives into the history behind some of the most notable infrastructure projects in the Greater Boston area leading up to The Big Dig, which became “a symbol of waste and corruption.”

Nancy and Ian talk through the notorious failures and unsung successes of the Big Dig, what we do with the lessons learned, and what it means for the future of our communities. Plus, we hear from people around the country about their experiences with massive infrastructure projects in their cities.
