Montpelier to New Castle Road Trip: A Deep Dive Through New England and the Mid-Atlantic

At 355 miles, this route from Vermont's capital to Delaware's historic river town traces the spine of the Eastern seaboard. The journey follows I-89 south, then I-91 and I-95, passing through five states and countless microclimates. A quirky fact: Montpelier is the only state capital without a McDonald's, while New Castle was briefly the capital of Delaware in the 17th century.

Interstate 95 through Connecticut and New York is notorious for congestion, but strategic timing can shave an hour off the drive. The route offers a rich tapestry of landscapes, from Vermont's Green Mountains to the tidal marshes of the Delaware River.
