Historian  David McCullough  is known for his biographies of monumental American figures: John Adams, Theodore Roosevelt, Harry S. Truman. But McCullough second book, published in 1972, explored American history not through the eyes of a Founding Father or a President, but through one of the most important public works projects of all time: the Brooklyn Bridge.
McCullough published  The Great Bridge  40 years ago. In honor of this anniversary,  Anna Sale, reporter for  It’s A Free Country, walked the Brooklyn Bridge with McCullough and discussed design, the Gilded Age, and whether the bridge could have been built today.
