Portland, ME to Pittsburgh, PA: Ultimate Road Trip Guide

The 800-mile journey from Portland, Maine to Pittsburgh, Pennsylvania takes you through six states and three distinct geological provinces: the New England coastal plain, the Appalachian Mountains, and the Allegheny Plateau. The route primarily follows I-95 S and I-84 W through southern Maine and New Hampshire, then I-81 S through the scenic Lehigh Valley and Susquehanna River corridor. A little-known fact: just west of Harrisburg, I-81 crosses the Blue Mountain ridge at Wind Gap, a site where continental glaciers deposited massive erratic boulders visible from the highway.
