David, a former Big Dig spokesperson, will tell the WHOLE story of of country's most expensive construction job. How Boston, straining for space to grow, cut down hills and filled in swamps and widened streets until the city was stalled in perpetual gridlock. Then we will journey deep inside the project's tunnels and soar high above the towers of Boston's stunning new bridge over the Charles River, and learn about the amazing technological advances used to build this monstrous project in a working city. And yes, and how the price climbed to a reported $22 billion. Whether you're interested in Boston history, a fan of technology, or just an angry taxpayer who wants to see the actual hole into which the government dumped your money, this is a must-see show.
