The Tappan Zee Bridge in New York

You would never look at a map of the Hudson River, point to the spot where the Tappan Zee Bridge is, and say, "Put the bridge here!"

The Tappan-Zee crosses one of the widest points on the Hudson — the bridge is more than three miles long. And if you go just a few miles south, the river gets much narrower.

Our question for today's show: Why did they build a three-mile-long bridge when they could have built a much shorter, cheaper bridge nearby?

Our search for an answer leads us to a forensic engineer, the Statue of Liberty, and a governor who wanted to be an opera singer.
