Here's how billions of dollars in cost overruns came to define Boston's Big Dig

Video Description

As they dug the tunnel below Boston's elevated Central Artery, an army of contractors encountered the subterranean infrastructure that powered the city - gas, thermal, electric, telephone and sewer lines. It slowed down work and drove up costs. But for six years the overall cost of the Big Dig never changed. This episode unravels the Big Dig's accounting and explores why cost overruns came to define the project. This is the sixth in a nine-part podcast series about history and politics of the Big Dig – one of the most notoriously troubled infrastructure projects in American history. It was created as an audio experience. This presentation includes archival images.
