As a Westerner who's never been to New England but loves history, I was very interested to learn about the Erie Canal. It was immensely consequential in developing the Westward expansion of the USA as well being a testament to the rugged determination and grit of the Irish immigrants who were its primary builders. Most amazingly, it was all dug with muscle power (and a healthy application of blasting powder) alone. It also cemented New York City as the financial and business center of the US.
