Portsmouth to West Point: A Complete Road Trip Guide

The route from Portsmouth, New Hampshire to West Point, New York spans approximately 250 miles, crossing three states: New Hampshire, Massachusetts, and New York. Most drivers follow I-95 South to I-84 West, then US-9W South, taking roughly 4.5 to 5 hours without stops.

However, the true value of this trip lies not in speed but in the rich tapestry of landscapes and history along the way. One striking fact: Portsmouth's historic Strawbery Banke Museum sits just 1.5 miles from I-95, while West Point's Thayer Gate is a stone's throw from US-9W, making detours easy.
