The Race Underground

In 1910, the Pennsylvania Railroad successfully accomplished the enormous engineering feat of building tunnels under New York City's Hudson and East Rivers, connecting the railroad to New York and New England, knitting together the entire eastern half of the United States. The tunnels terminated in what was one of the greatest architectural achievements of its time, Pennsylvania Station. Penn Station covered nearly eight acres, extended two city blocks, and housed one of the largest public spaces in the world. But just 53 years after the station’s opening, the monumental building that was supposed to last forever, to herald and represent the American Empire, was slated to be destroyed.

On September 16, 1920, as hundreds of Wall Street workers headed out for lunch, a horse-drawn cart packed with dynamite exploded in front of Morgan Bank — the world’s most powerful banking institution.

As financial institutions around the country went on high alert, many wondered if this was the strike against American capitalism that radical agitators had threatened for so long.

In May of 1942, across the rugged sub-Arctic wilderness of Alaska and Canada, thousands of American soldiers began one of the biggest and most difficult construction projects ever undertaken-building the Alaska Highway.
